'Acted' in the Bible

"Brethren, it was necessary that the Scripture should be fulfilled--the prediction, I mean, which the Holy Spirit uttered by the lips of David, about Judas, who acted as guide to those who arrested Jesus.

And that was how I acted in Jerusalem. Armed with authority received from the High Priests I shut up many of God's people in various prisons, and when they were about to be put to death I gave my vote against them.
