'We are Witnesses' in the Bible

And Joshua said to the people, Ye are witnesses against yourselves that ye have chosen you the LORD, 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. The LORD make the woman that hath come into thy house like Rachel and like Leah, which two did build the house of Israel: and do thou worthily in Ephratah, and be famous in Beth-lehem:

And killed the Prince of life, whom God hath raised from the dead; of which we are witnesses.

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.
