3 So all the elders of Israel came to the king at Hebron, and King David made a covenant with them at Hebron before the Lord, and they anointed David king over Israel. 4 David was thirty years old when he began to reign, and he reigned forty years. 5 At Hebron he reigned over Judah seven years and six months, and at Jerusalem he reigned over all Israel and Judah thirty-three years.
