I Samuel 10:7-9, 24, 26

And let it be, when these signs come to you, that you do as the occasion demands; for God is with you. You shall go down before me to Gilgal; and surely I will come down to you to offer burnt offerings and make sacrifices of peace offerings. Seven days you shall wait, till I come to you and show you what you should do.” So it was, when he had turned his back to go from Samuel, that God gave him another heart; and all those signs came to pass that day.

And Samuel said to all the people, “Do you see him whom the LORD has chosen, that there is no one like him among all the people?” So all the people shouted and said, “Long live the king!”

And Saul also went home to Gibeah; and valiant men went with him, whose hearts God had touched.
