2 Samuel 5:1-5 - David Anointed As King Over All Of Israel
1 After this, all of the tribes of Israel assembled with David at Hebron and declared, "Look, we're your own flesh and blood! 2 Even back when Saul was our king, it was you who kept on leading Israel out to battle and bringing them back again. The LORD told you, "You yourself will shepherd my people Israel and serve as Commander-in-Chief over Israel.'"
3 So all the elders of Israel approached the king at Hebron, where King David entered into a covenant with them in the presence of the LORD. Then they anointed David to be king over Israel.
4 David began to reign when he was 30 years old, and he reigned 40 years. 5 He reigned over Judah for seven years and six months in Hebron, and he reigned over all of Israel including Judah for 33 years in Jerusalem.
