2 Samuel 5:3-5

BSB(i) 3 So all the elders of Israel came to the king at Hebron, where King David made with them a covenant before the LORD. And they anointed him king over Israel. 4 David was thirty years old when he became king, and he reigned forty years. 5 In Hebron he reigned over Judah seven years and six months, and in Jerusalem he reigned thirty-three years over all Israel and Judah.
