1 Samuel 10:5-6, 10-13

After that you shall come to Gibeath-elohim, where there is a garrison of the Philistines. And there, as soon as you come to the city, you will meet a group of prophets coming down from the high place with harp, tambourine, flute, and lyre before them, prophesying. Then the Spirit of the LORD will rush upon you, and you will prophesy with them and be turned into another man.

When they came to Gibeah, behold, a group of prophets met him, and the Spirit of God rushed upon him, and he prophesied among them. And when all who knew him previously saw how he prophesied with the prophets, the people said to one another, “What has come over the son of Kish? Is Saul also among the prophets?” And a man of the place answered, “And who is their father?” Therefore it became a proverb, “Is Saul also among the prophets?” When he had finished prophesying, he came to the high place.
