1 Samuel 10:6-8, 13

The Spirit of the LORD will come powerfully upon you, and you will prophesy with them; and you will be changed into a different person. Once these signs are fulfilled, do whatever your hand finds to do, for God is with you. “Go down ahead of me to Gilgal. I will surely come down to you to sacrifice burnt offerings and fellowship offerings, but you must wait seven days until I come to you and tell you what you are to do.”

After Saul stopped prophesying, he went to the high place.
