'Witness' in the Bible

beginning from the baptism of John until the day He was taken up from us—from among these, it is necessary that one become a witness with us of His resurrection.”

although He did not leave Himself without a witness, since He did what is good by giving you rain from heaven and fruitful seasons and satisfying your hearts with food and happiness.”

For you will be a witness for Him to all people of what you have seen and heard.

And when the blood of Your witness Stephen was being shed, I was standing by and approving, and I guarded the clothes of those who killed him.’

But get up and stand on your feet. For I have appeared to you for this purpose, to appoint you as a servant and a witness of what you have seen and of what I will reveal to you.
