1 Samuel 10:3-7

Then you will go on farther from there, and you will come as far as the oak of Tabor, and there three men going up to God at Bethel will meet you: one carrying three young goats, another carrying three loaves of bread, and another carrying a jug of wine.

And they will greet you and give you two loaves of bread, which you will accept from their hand.

Afterward you will come to the hill of God where the Philistine garrison is; and it shall be as soon as you have come there to the city, that you will meet a group of prophets coming down from the high place with harp, tambourine, flute, and a lyre in front of them, and they will be prophesying.

Then the Spirit of the Lord will rush upon you, and you will prophesy with them and be changed into a different man.

And it shall be when these signs come to you, do for yourself what the occasion requires, because God is with you.
