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 art come thither to the city, that thou shalt meet a band of prophets coming down from the high place with a psaltery, and a timbrel, and a pipe, and a harp, before them; and they will be prophesying:

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