And ye also shall bear witness, because ye have been with me from the beginning.
But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
Wherefore of these men which have companied with us all the time that the Lord Jesus went in and out among us, Beginning from the baptism of John, unto that same day that he was taken up from us, must one be ordained to be a witness with us of his resurrection.
This Jesus hath God raised up, whereof we all are witnesses.
And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses.
And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all.
And we are his witnesses of these things; and so is also the Holy Ghost, whom God hath given to them that obey him.
And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree: Him God raised up the third day, and shewed him openly; Not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead.
And he was seen many days of them which came up with him from Galilee to Jerusalem, who are his witnesses unto the people.

1 John 1:1-3
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; (For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;) That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.
