Study Notes

kingdom of our God
The Dispensation of the Kingdom ( 2 Samuel 7:16 refs.) begins with the return of Christ to the earth, runs through the "thousand years" of His earth-rule, and ends when He has delivered up the kingdom to the Father.
salvation .
kingdom
Kingdom (N.T.), Summary: See "Kingdom (O.T.)" Genesis 1:26-28 . (See Scofield " Zechariah 12:8 ") . Kingdom truth is developed in the N.T. in the following order:
(1) The promise of the kingdom to David and his seed, and described in the prophets 2 Samuel 7:8-17 ,; Zechariah 12:8 enters the N.T. absolutely unchanged. Luke 1:31-33 . The King was born in Bethlehem; Matthew 2:1 ; Micah 5:2 of a virgin.; Matthew 1:18-25 ; Isaiah 7:14 .
(2) The kingdom announced as "at hand" (See Scofield " Matthew 4:17 ") , by John the Baptist, by the King, and by the Twelve, was rejected by the Jews, first morally, See Scofield " Matthew 11:20 ", and afterward officially Matthew 21:42 ; Matthew 21:43 and the King, crowned with thorns, was crucified.
(3) In anticipation of His official rejection and crucifixion, the King revealed the "mysteries" of the kingdom of heaven, (See Scofield " Matthew 13:11 ") to be fulfilled in the interval between His rejection and His return in glory Matthew 13:1-50 .
(4) Afterward He announced His purpose to "build" His church Matthew 16:18 another "mystery" revealed through Paul which is being fulfilled contemporaneously with the mysteries of the kingdom. The "mysteries of the kingdom of heaven" and the "mystery" of the church Ephesians 3:9-11 occupy, historically, the same period, i.e, this present age.
(5) The mysteries of the kingdom will be brought to an end by "the harvest" Matthew 13:39-43 ; Matthew 13:49 ; Matthew 13:50 at the return of the King in glory, the church having previously been caught up to meet Him in the air 1 Thessalonians 4:14-17 .
(6) Upon His return the King will restore the Davidic monarchy in His own person, re- gather dispersed Israel, establish His power over all the earth, and reign one thousand years Matthew 24:27-30 ; Luke 1:31-33 ; Acts 15:14-17 ; Revelation 20:1-10 .
(7) The kingdom of heaven (See Scofield " Matthew 3:2 ") thus established under David's divine Son, has for its object the restoration of the divine authority in the earth, which may be regarded as a revolted province of the great kingdom of God See Scofield " Matthew 6:33 ". When this is done ( 1 Corinthians 14:24 ; 1 Corinthians 14:25 ) the Son will deliver up the kingdom (of heaven), Matthew 3:2 to "God, even the Father," that "God" (i.e. the triune God, Father, Son, and Holy Spirit) "may be all in all" ( 1 Corinthians 14:28 ). The eternal throne is that "of God, and of the Lamb" Revelation 22:1 . The kingdom-age constitutes the seventh Dispensation, See Scofield " Ephesians 1:10 ".
Then cometh Then, finally, when he delivers up the kingdom to God, even the Father; when he has done away with every rule, and every authority and power (for he must reign till he has put all enemies under his feet), the last enemy, death, is destroyed.
salvation
The Heb. and (Greek - ἀλεκτοροφωνία , safety, preservation, healing, and soundness). Salvation is the great inclusive word of the Gospel, gathering into itself all the redemptive acts and processes: as justification, redemption, grace, propitiation, imputation, forgiveness, sanctification, and glorification. Salvation is in three tenses:
(1) The believer has been saved from the guilt and penalty of sin Luke 7:50 ; 1 Corinthians 1:18 ; 2 Corinthians 2:15 ; Ephesians 2:5 ; Ephesians 2:8 ; 2 Timothy 1:9 and is safe.
(2) the believer is being saved from the habit and dominion of sin Romans 6:14 ; Philippians 1:19 ; Philippians 2:12 ; Philippians 2:13 ; 2 Thessalonians 2:13 ; Romans 8:2 ; Galatians 2:19 ; Galatians 2:20 ; 2 Corinthians 3:18 .
(3) The believer is to be saved in the sense of entire conformity to Christ. Romans 13:11 ; Hebrews 10:36 ; 1 Peter 1:5 ; 1 John 3:2 . Salvation is by grace through faith, is a free gift, and wholly without works; Romans 3:27 ; Romans 3:28 ; Romans 4:1-8 ; Romans 6:23 ; Ephesians 2:8 . The divine order is: first salvation, then works; Ephesians 2:9 ; Ephesians 2:10 ; Titus 3:5-8 .

Verse Meaning

John then heard another outburst of praise in heaven. This one seems to have come from the Tribulation martyrs ( Revelation 6:10; cf. Revelation 12:10). Their rejoicing is proleptic anticipating the imminent expulsion of Satan. God"s salvation (victory), the manifestation of His power, and His kingdom (both the millennial and eternal phases) will have come even closer when this happens. Likewise the manifestation of the authority of His Anointed One will be nearer (cf. Revelation 11:15; Psalm 2:8). The way will then be more open than it was previously for the establishment of God"s kingdom on the earth.
Satan"s malevolent work of accusing believers before God will cease (cf. Job 1:6). However, he will continue to persecute the living brethren of the martyrs still on earth even though he can no longer accuse them in heaven. Satan accused believers day and night (constantly), just as steadily as the four living beings praise God ( Revelation 4:8).

Context Summary

Revelation 12:7-17 - Satan Cast Down From Heaven
The spirit of evil waits to destroy each birth of good in our world. As soon as Mary had given birth to our Lord, Herod sought to destroy Him, and this is characteristic of all the ages. But God's care is always at hand to deliver His own. He has His prepared places, where He hides those who trust in Him. He keeps them in the secret of His pavilion from the strife of men.
Sin has brought conflict, not on our earth only, but throughout the universe; but from the heavenly places it has been driven, and the last stand is made on our earth. Is it not possible that the awful war which has desolated mankind may be one of the last phases of this age-long conflict? There is but one talisman of victory. We overcome only in so far as we take shelter in the blood of the Lamb and wield as our weapon the Word of God. As darkness cannot resist the light, so evil cannot exist before the witness of the Church and the child of God, if only we care more for the honor and glory of Christ than for our own lives. To the end there must be war between the seed of the woman and the dragon, and there must be bruising. But the final outcome is sure. As Satan was cast out of heaven, so he shall be cast out of earth, and Christ shall see of the travail of his soul and shall be satisfied. [source]

A great voice saying [πωνην μεγαλην λεγουσαν]
Accusative after ηκουσα — ēkousa in this phrase as in Revelation 5:11; Revelation 10:4; Revelation 14:2; Revelation 18:4, but the genitive πωνης λεγουσης — phōnēs legousēs in Revelation 11:12; Revelation 14:13.

Salvation, power, the kingdom []
All have the article: the salvation, etc. So Rev. The phrase, now is come the salvation, etc., means that these are realized and established. Some, less correctly, render, now is the salvation, etc., become our God's. Compare Luke 3:6. [source]
Power [ἐξουσία]

The accuser of our brethren [ὁ κατήγορος τῶν ἀδελφῶν ἡμῶν]
The correct form of the Greek for accuser is a transcript of the Rabbinical Hebrew, κατήγωρ . The Rabbins had a corresponding term συνήγωρ for Michael, as the advocate of God's people. The phrase is applied to Satan nowhere else in the New Testament. [source]
Is cast down [κατεβλήθη]
The aorist tense. Once and for all. Compare John 12:31; John 16:8, John 16:11. [source]
Which accuseth [ὁ κατηγορῶν]
Lit., the one. The article with the present participle expresses what is habitual. [source]

Reverse Greek Commentary Search for Revelation 12:10

John 5:45 I will accuse [κατηγορήσω]
From κατά , against, and ἀγορεύω , to speak in the assembly ( ἀγορά ). Hence, properly, to bring an accusation in court. John uses no other verb for accuse, and this only here, John 8:6, and Revelation 12:10. Once in the New Testament διαβάλλω occurs (Luke 16:1, on which see note), signifying malicious accusation, and secret, as distinguished from public, accusation ( κατηγορία ). Αἰτιάομαι occurs once in the compound προῃτιασάμεθα , we before laid to the charge (Romans 3:9). This has reference especially to the ground of accusation ( αἰτία ). Ἑγκαλέω occurs only in Acts, with the exception of Romans 8:33. It means to accuse publicly, but not necessarily before a tribunal. See Acts 23:28, Acts 23:29; Acts 26:2, Acts 26:7. [source]
1 Timothy 3:6 Of the devil [τοῦ διαβόλου]
See on Matthew 4:1, and see on Satan, 1 Thessalonians 2:18. Paul uses διάβολος only twice, Ephesians 4:27; Ephesians 6:11. Commonly Satan. The use of διάβολος as an adjective is peculiar to the Pastorals (see 1 Timothy 3:11; 2 Timothy 3:3; Titus 2:3), and occurs nowhere else in N.T., and not in lxx. The phrase judgment of the devil probably means the accusing judgment of the devil, and not the judgment passed upon the devil. In Revelation 12:10Satan is called the accuser of the brethren. In 1 Corinthians 5:5; 1 Timothy 1:20, men are given over to Satan for judgment. In 1 Timothy 3:7the genitive διαβόλου isclearly subjective. In this chapter it appears that a Christian can fall into the reproach of the devil (comp. Judges 1:9; 2 Peter 2:11), the snare of the devil (comp. 2 Timothy 2:26), and the judgment of the devil. [source]
1 John 4:14 The Savior of the world []
See the same phrase, John 4:42, and compare John 3:17. Σωτήρ Savioroccurs in John only here and John 4:42. Elsewhere it is applied both to God (1 Timothy 1:1; 1 Timothy 2:3; Titus 1:3; Titus 2:10; Titus 3:4; Judges 1:25), and to Christ (Luke 2:11; Acts 5:31; Acts 13:23; 2 Timothy 1:10; Titus 1:4, etc.). The title is found in Paul's Epistles of the Captivity (Ephesians 5:23; Philemon 3:20), and in the Pastorals (see above), but not in Corinthians, Romans, Galatians, or Thessalonians. In classical writings the term is applied to many deities, especially to Zeus (Jupiter); also to Hermes (Mercury), Apollo, Hercules, and even to female deities, as Fortune and Aphrodite (Venus). “Zeus Soter” (Zeus Savior) was used as a formula in drinking at banquets. The third cup was dedicated to him. Compare Plato: “Then, by way of a third libation to the savior Zeus, let us sum up and reassert what has been said” (“Philebus,” 66). The drinking of this cup was a symbol of good fortune, and the third time came to mean the lucky time. “Twice then has the just man overthrown the unjust; and now comes the third trial, which, after Olympic fashion, is sacred to Zeus the savior, … and surely this will prove the greatest and most decisive of falls” (Plato, “Republic,” 583). Hence the proverb, τὸ τρίτον τῳ σωτῆρι , lit., the third to the savior; i.e., the third or lucky time. The name was also given later to princes or public benefactors. The kindred noun σωτηρία salvationdoes not occur in John's Epistles, and appears only once in the Gospel (John 4:22). It is found thrice in Revelation (Revelation 7:10; Revelation 12:10; Revelation 19:1). Σώζειν tosave occurs six times in John's Gospel, and once in Revelation (Revelation 21:24). It does not appear in the Epistles. [source]
1 John 2:13 The evil one [τὸν πονηρόν]
See on wickedness, Mark 7:22; see on evils, Luke 3:19; see on evil spirits, Luke 7:21. The prince of darkness is styled by John ὁ διάβολος thefalse accuser (John 8:44; John 13:2; 1 John 3:8, 1 John 3:10. See on Matthew 4:1): ὁ Σατανᾶς Satanthe adversary (John 13:27; compare ὁ κατήγωρ theaccuser, properly, in court, Revelation 12:10): ὁ πονηρός theevil one (John 17:15; 1 John 2:13, 1 John 2:14; 1 John 3:12; 1 John 5:18, 1 John 5:19): ὁ ἄρχων τοῦ κόσμου τούτου theruler of this world (John 12:31; John 14:30; John 16:11). Note the abrupt introduction of the word here, as indicating something familiar. [source]
Revelation 11:12 Saying [λεγουσης]
Present active predicate participle of λεγω — legō feminine genitive agreeing with πωνης — phōnēs though some MSS. have the accusative πωνην λεγουσαν — phōnēn legousan either construction being proper after ηκουσαν — ēkousan (they heard). There is a little evidence for ηκουσα — ēkousa like Revelation 12:10 (24 times in the book). Cf. John 5:28. [source]
Revelation 12:10 The accuser [ο κατηγωρ]
The regular form, κατηγορος — katēgoros occurs in John 8:10; Acts 23:30, Acts 23:35; Acts 25:16, Acts 25:18 and in many MSS. here in Revelation 12:10, but A reads κατηγωρ — katēgōr which Westcott and Hort accept. It was once considered a Greek transliteration of a Hebrew word, but Deissmann (Light, etc., p. 93f.) quotes it from a vernacular magical papyrus of the fourth century a.d. with no sign of Jewish or Christian influence, just as διακων — diakōn appears as a vernacular form of διακονος — diakonos Only here is the word applied to Satan in the N.T. In late Judaism Satan is the accuser, and Michael the defender, of the faithful. [source]
Revelation 12:12 Therefore [δια τουτο]
“For this reason” as in Revelation 7:15; Revelation 18:8 (15 times in John‘s Gospel, Charles notes). It points back to Revelation 12:10. [source]
Revelation 12:13 He persecuted [εδιωχεν]
First aorist active participle of διωκω — diōkō to pursue, to chase, hostile pursuit here as in Matthew 5:10.; Matthew 10:23, etc. John now, after the “voice” in Revelation 12:10-13, returns to the narrative in Revelation 12:9. The child was caught away in Revelation 12:5, and now the woman (the true Israel on earth) is given deadly persecution. Perhaps events since a.d. 64 (burning of Rome by Nero) amply illustrated this vision, and they still do so. [source]
Revelation 19:1 Saying [λεγοντων]
Present active participle of λεγω — legō genitive plural, though οχλου — ochlou is genitive singular (collective substantive, agreement in sense).Hallelujah (Αλληλουια — Allēlouia). Transliteration of the Hebrew seen often in the Psalms (lxx) and in 3 Macc. 7:13, in N.T. only in Revelation 19:1, Revelation 19:3, Revelation 19:4, Revelation 19:6. It means, “Praise ye the Lord.” Fifteen of the Psalms begin or end with this word. The Great Hallel (a title for Psalm 104-109) is sung chiefly at the feasts of the passover and tabernacles. This psalm of praise uses language already in Revelation 12:10. [source]
Revelation 12:10 Now is come [αρτι εγενετο]
Αρτι — Arti (John 13:33) shows how recent the downfall of Satan here proleptically pictured as behind us in time (aorist tense εγενετο — egeneto).The salvation (η σωτηρια — hē sōtēria). Here “the victory” as in Revelation 7:10; Revelation 19:1.The power Gods power over the dragon (cf.
