3 And all the elders of Israel came to the king to Hebron; and king David made a covenant with them in Hebron before Jehovah; and they anointed David king over Israel. 4 David was thirty years old when he began to reign; he reigned forty years.
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.
