All the tribes of Israel came to David at Hebron and said, “We are your own flesh and blood.
In the past, while Saul was king over us, you were the one who led Israel on their military campaigns. And the LORD said to you, ‘You will shepherd my people Israel, and you will become their ruler.’ ”
When all the elders of Israel had come to King David at Hebron, the king made a covenant with them at Hebron before the LORD, and they anointed David king over Israel.
David was thirty years old when he became king, and he reigned forty years.
