'We are Witnesses' in the Bible

And Joshua said unto the people, Ye are witnesses against yourselves that ye have chosen you Jehovah, to serve him. And they said, We are witnesses.

And all the people that were in the gate, and the elders, said, We are witnesses. Jehovah make the woman that is come into thy house like Rachel and like Leah, which two did build the house of Israel: and do thou worthily in Ephrathah, and be famous in Bethlehem:

and killed the Prince of life; whom God raised from the dead; whereof we are witnesses.

And we are witnesses of these things; and'so is the Holy Spirit, whom God hath given to them that obey him.

And we are witnesses of all things which he did both in the country of the Jews, and in Jerusalem; whom also they slew, hanging him on a tree.
