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, Ps 110:2,3.
13. And say ye to Amasa, &c.—This also was a dextrous stroke of policy. David was fully alive to the importance, for extinguishing the rebellion, of withdrawing from that cause the only leader who could keep it alive; and he, therefore, secretly intimated his intention to raise Amasa to the command of the army in the place of Joab, whose overbearing haughtiness had become intolerable. The king justly reckoned, that from natural temper as well as gratitude for the royal pardon, he would prove a more tractable servant; and David, doubtless, intended in all sincerity to fulfil this promise. But Joab managed to retain his high position (see on 2Sa 20:4-10).
