1 Samuel 9:1-2, 15-21, 27 (NIV):
[9] There was a Benjamite, a man of standing, whose name was Kish son of Abiel, the son of Zeror, the son of Bekorath, the son of Aphiah of Benjamin.

[15] Now the day before Saul came, the Lord had revealed this to Samuel: [16] “About this time tomorrow I will send you a man from the land of Benjamin. Anoint him ruler over my people Israel; he will deliver them from the hand of the Philistines. I have looked on my people, for their cry has reached me.”

[17] When Samuel caught sight of Saul, the Lord said to him, “This is the man I spoke to you about; he will govern my people.”

[18] Saul approached Samuel in the gateway and asked, “Would you please tell me where the seer’s house is?”

[19] “I am the seer,” Samuel replied. “Go up ahead of me to the high place, for today you are to eat with me, and in the morning I will send you on your way and will tell you all that is in your heart. [20] As for the donkeys you lost three days ago, do not worry about them; they have been found. And to whom is all the desire of Israel turned, if not to you and your whole family line?”

[21] Saul answered, “But am I not a Benjamite, from the smallest tribe of Israel, and is not my clan the least of all the clans of the tribe of Benjamin? Why do you say such a thing to me?”

[27] As they were going down to the edge of the town, Samuel said to Saul, “Tell the servant to go on ahead of us”—and the servant did so—“but you stay here for a while, so that I may give you a message from God.”

1 Samuel 10:1-7, 9 (NIV):
[1] Then Samuel took a flask of olive oil and poured it on Saul’s head and kissed him, saying, “Has not the Lord anointed you ruler over his inheritance? [2] When you leave me today, you will meet two men near Rachel’s tomb, at Zelzah on the border of Benjamin. They will say to you, ‘The donkeys you set out to look for have been found. And now your father has stopped thinking about them and is worried about you. He is asking, “What shall I do about my son?”’

[3] “Then you will go on from there until you reach the great tree of Tabor. Three men going up to worship God at Bethel will meet you there. One will be carrying three young goats, another three loaves of bread, and another a skin of wine. [4] They will greet you and offer you two loaves of bread, which you will accept from them.

[5] “After that you will go to Gibeah of God, where there is a Philistine outpost. As you approach the town, you will meet a procession of prophets coming down from the high place with lyres, timbrels, pipes and harps being played before them, and they will be prophesying. [6] The Spirit of the Lord will come powerfully upon you, and you will prophesy with them; and you will be changed into a different person. [7] Once these signs are fulfilled, do whatever your hand finds to do, for God is with you.

[9] As Saul turned to leave Samuel, God changed Saul’s heart, and all these signs were fulfilled that day.
