1 Samuel 10:6-10

Then the Spirit of the Lord will rush upon you, and you will prophesy with them and be changed into a different man.

And it shall be when these signs come to you, do for yourself what the occasion requires, because God is with you.

And you shall go down ahead of me to Gilgal; and behold, I will be coming down to you to offer burnt offerings and sacrifice peace offerings. You shall wait seven days until I come to you and inform you of what you should do.”

Then it happened, when he turned his back to leave Samuel, that God changed his heart; and all those signs came about on that day.

When they came there to the hill, behold, a group of prophets met him; and the Spirit of God rushed upon him, so that he prophesied among them.
