1 Samuel 10:5-6

5After that thou shalt come to the hill of God, where is the garrison of the Philistines: and it shall come to pass, when thou hast come there to the city, that thou shalt meet a company of prophets coming down from the high place with a psaltery, and a tabret, and a pipe, and a harp, before them; and they shall prophesy:

6And the Spirit of the LORD will come upon thee, and thou shalt prophesy with them, and shalt be turned into another man.
