I Samuel 9:15-17

Now the LORD had told Samuel in his ear the day before Saul came, saying, “Tomorrow about this time I will send you a man from the land of Benjamin, and you shall anoint him commander over My people Israel, that he may save My people from the hand of the Philistines; for I have looked upon My people, because their cry has come to Me.” So when Samuel saw Saul, the LORD said to him, “There he is, the man of whom I spoke to you. This one shall reign over My people.”
