Luke 24:48

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.

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:

And he was seen many days of them which came up with him from Galilee to Jerusalem, who are his witnesses unto the people.

For thou shalt be his witness unto all men of what thou hast seen and heard.
