13 And say ye to Amasa, Art thou not my bone and my flesh? God do so to me, and more also, if thou be not captain of the host before me continually in the room of Joab.

Matthew Henry's Commentary on 2 Samuel 19:13

Commentary on 2 Samuel 19:9-15

(Read 2 Samuel 19:9-15)

God's providence, by the priests' persuasions and Amasa's interest, brought the people to resolve the recall of the king. David stirred not till he received this invitation. Our Lord Jesus will rule in those that invite him to the throne in their hearts, and not till he is invited. He first bows the heart, and makes it willing in the day of his power, then rules in the midst of his enemies, Psalm 110:2,3.
