2 Samuel 5:1-5

Before long all the tribes of Israel approached David in Hebron and said, “Look at us—your own flesh and blood! In time past when Saul was our king, you were the one who really ran the country. Even then GOD said to you, ‘You will shepherd my people Israel and you’ll be the prince.’” All the leaders of Israel met with King David at Hebron, and the king made a treaty with them in the presence of GOD. And so they anointed David king over Israel. * * * David was thirty years old when he became king, and ruled for forty years. In Hebron he ruled Judah for seven and a half years. In Jerusalem he ruled all Israel and Judah for thirty-three years.
