1 Samuel 9:15-16
15-16The very day before, God had confided in Samuel, "This time tomorrow, I'm sending a man from the land of Benjamin to meet you. You're to anoint him as prince over my people Israel. He will free my people from Philistine oppression. Yes, I know all about their hard circumstances. I've heard their cries for help."
17The moment Samuel laid eyes on Saul, God said, "He's the one, the man I told you about. This is the one who will keep my people in check."
