1 Samuel 10:9

Then the LORD’s Spirit will come mightily on you, then you will prophesy with them and will be turned into another man.

Let it be, when these signs have come to you, that you do what is appropriate for the occasion; for God is with you.

“Go down ahead of me to Gilgal; and behold, I will come down to you to offer burnt offerings and to sacrifice sacrifices of peace offerings. Wait seven days, until I come to you and show you what you are to do.”

When they came there to the hill, behold, a band of prophets met him; and the Spirit of God came mightily on him, and he prophesied among them.

When all who knew him before saw that, behold, he prophesied with the prophets, then the people said to one another, “What is this that has come to the son of Kish? Is Saul also among the prophets?”

One from the same place answered, “Who is their father?” Therefore it became a proverb, “Is Saul also among the prophets?”
