1 Samuel 10:5-6, 10-13

“When you arrive at Gibeah of God, where the garrison of the Philistines is located, you will meet a band of prophets coming down from the place of worship. They will be playing a harp, a tambourine, a flute, and a lyre, and they will be prophesying. At that time the Spirit of the LORD will come powerfully upon you, and you will prophesy with them. You will be changed into a different person.

When Saul and his servant arrived at Gibeah, they saw a group of prophets coming toward them. Then the Spirit of God came powerfully upon Saul, and he, too, began to prophesy. When those who knew Saul heard about it, they exclaimed, “What? Is even Saul a prophet? How did the son of Kish become a prophet?” And one of those standing there said, “Can anyone become a prophet, no matter who his father is?” So that is the origin of the saying “Is even Saul a prophet?” When Saul had finished prophesying, he went up to the place of worship.
