The Lord told Zechariah that He had been angry with the Jews" forefathers. Therefore, the prophet was to preach repentance to his contemporaries as Yahweh"s authoritative and faithful mouthpiece. If they turned back to the Lord, He would return to bless them (cf. Isaiah 55:6-7; Jeremiah 3:12; Hosea 7:10; Joel 2:12-13; Amos 5:4; Amos 5:6; Malachi 3:7). This is the clarion call that furnishes the background for this book"s message of hope. [1] And this was the reassurance that the restoration community needed after the discipline of the Exile. They were to return to Yahweh, to a personal relationship and allegiance to Him, not just to formal obedience to His law and covenant. Zechariah was to warn the Israelites not to be like their (pre-exilic) forefathers who refused to respond to the preaching of earlier (pre-exilic) prophets who urged them to repent (e.g, Isaiah ,, Jeremiah , et al.).
