1 Samuel 10:3-7

3Then you will go on further from there, and you will come to the terebinth tree of Tabor, and three men going up to [sacrifice to] God at Bethel will meet you there, one carrying three young goats, another carrying three loaves of bread, and another carrying a jug of wine.

4They will greet you and give you two loaves of bread, which you will accept from their hand.

5After that you will come to the hill of God where the garrison of the Philistines is; and when you come there to the city, you will meet a group of prophets coming down from the high place [of worship] with harp, tambourine, flute, and lyre before them, and they will be prophesying.

6Then the Spirit of the Lord will come upon you mightily, and you will prophesy with them, and you will be changed into another man.

7When these signs come to you, do for yourself whatever the situation requires, for God is with you.
