1 Samuel 10:1-16
Then Samuel took a vial of oil and poured it on his head, and kissed him and said, "Has not the LORD anointed you to be prince over his people Israel? And you shall reign over the people of the LORD and you will save them from the hand of their enemies round about. And this shall be the sign to you that the LORD has anointed you to be prince over his heritage. When you depart from me today you will meet two men by Rachel's tomb in the territory of Benjamin at Zelzah, and they will say to you, 'The asses which you went to seek are found, and now your father has ceased to care about the asses and is anxious about you, saying, "What shall I do about my son?"' Then you shall go on from there further and come to the oak of Tabor; three men going up to God at Bethel will meet you there, one carrying three kids, another carrying three loaves of bread, and another carrying a skin of wine. And they will greet you and give you two loaves of bread, which you shall accept from their hand. After that you shall come to Gib'e-ath-elo'him, where there is a garrison of the Philistines; and there, as you come to the city, you will meet a band of prophets coming down from the high place with harp, tambourine, flute, and lyre before them, prophesying. Then the spirit of the LORD will come mightily upon you, and you shall prophesy with them and be turned into another man. Now when these signs meet you, do whatever your hand finds to do, for God is with you. And you shall go down before me to Gilgal; and behold, I am coming to you to offer burnt offerings and to sacrifice peace offerings. Seven days you shall wait, until I come to you and show you what you shall do."
When he turned his back to leave Samuel, God gave him another heart; and all these signs came to pass that day. When they came to Gib'e-ah, behold, a band of prophets met him; and the spirit of God came mightily upon him, and he prophesied among them. And when all who knew him before 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. Saul's uncle said to him and to his servant, "Where did you go?" And he said, "To seek the asses; and when we saw they were not to be found, we went to Samuel." And Saul's uncle said, "Pray, tell me what Samuel said to you." And Saul said to his uncle, "He told us plainly that the asses had been found." But about the matter of the kingdom, of which Samuel had spoken, he did not tell him anything.
