I Samuel 10:6-8, 13

Then the Spirit of the LORD will come upon you, and you will prophesy with them and be turned into another man. 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.”

And when he had finished prophesying, he went to the high place.
