'We are Witnesses' in the Bible

Joshua then said to the people, “You are witnesses against yourselves that you have chosen for yourselves the Lord, to serve Him.” And they said, “We are witnesses.”

All the people at the gate and the elders said, “We are witnesses. May the Lord make the woman who is coming into your house like Rachel and Leah, the two who built the household of Israel. May you achieve wealth and power in Ephrathah and become famous in Bethlehem.

But you killed the Prince (Author, Originator, Source) of life, whom God raised [bodily] from the dead. To this [fact] we are witnesses [for we have seen the risen Christ].

And we are witnesses of these things; and so is the Holy Spirit, whom God has bestowed on those who obey Him.”
