51 Then came all the tribes of Israel to David to Hebron, and spoke, saying, “Behold, we are your bone and your flesh. 2 In times past, when Saul was king over us, it was you who led out and brought in Israel. Yahweh said to you, ‘You shall be shepherd of my people Israel, and you shall be prince over Israel.’” 3 So all the elders of Israel came to the king to Hebron; and king David made a covenant with them in Hebron before Yahweh; and they anointed David king over Israel. 4 David was thirty years old when he began to reign, 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.

Commentary on 2 Samuel 5:1-5
(Read 2 Samuel 5:1-5)
David was anointed king a third time. His advances were gradual, that his faith might be tried, and that he might gain experience. Thus his kingdom typified that of the Messiah, which was to come to its height by degrees. Thus Jesus became our Brother, took upon him our nature, dwelt in it that he might become our Prince and Saviour: thus the humbled sinner takes encouragement from the endearing relation, applies for his salvation, submits to his authority, and craves his protection.
