'Gave Testimony' in the Bible

And when he had removed him, he raised up unto them David to be their king; to whom also he gave testimony, and said, I have found David the son of Jesse, a man after my own heart, who shall fulfill all my will.

A long time therefore abode they speaking boldly in the Lord, who gave testimony unto the word of his grace, and granted signs and wonders to be done by their hands.
