Of my bone ... - Render as in preceding verse, "art thou not my bone and my flesh?" It is curious to note how the phrase is used in 2 Samuel 5:1 of common descent from Israel, in 2 Samuel 19:12 of the closer kindred of the tribe of Judah, and in this verse of the yet nearer kindred between David and Amasa his sister's son.

Captain ... in the room of Joab - It is very plain that David felt the weight of Joab's overbearing influence to be very oppressive (compare 2 Samuel 19:22; 2 Samuel 3:39; 2 Samuel 16:10). He was, at this time, very angry with Joab for killing Absalom; and so, thinking it of vital importance to win over Amasa and the army of Judah, he did not scruple to offer him Joab's high post.

And say ye to Amasa,.... Who was the general of Absalom's army, and who might fear he should never be pardoned, whoever was, and looked upon his case as desperate; who had led on the army with Absalom against the king's threes, and fought them:

art thou not of my bone, and of my flesh? nearly related to him, being his sister's son:

God do so to me, and more also: than he had done to Absalom; or he imprecates the greatest evil upon himself that could be thought of or named:

if thou be not captain of the host before me continually in the room of Joab; signifying that he would not only pardon the treason he had been guilty of, but raise him to the highest post in the army; and to assure him of it, of which he might be doubtful, considering what he had done to merit his displeasure, he makes this oath or imprecation. Joab had got his ill will by many instances, as by the murder of Abner, and now by slaying Absalom against his orders; and by his rude and insolent behaviour to him when lamenting the death of his son; he wanted to be rid of him, and now, having an opportunity of putting a valiant man into his place, and thereby attaching him to his interest, he was determined to make use of it.

"And say ye to Amasa, Art thou not my bone and flesh? so shall God do to me, and so add, if thou shalt not be prince of the army (chief captain) before me continually in the place of Joab."

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

(f) By this policy David thought that by winning the captain, he would have the hearts of all the people.

19:13 Of Joab - Who, besides his other crimes, had lately exasperated the king by his murder of Absalom, contrary to David's express command. And therefore the king having now the opportunity of another person who had a greater interest than Joab, gladly complies with it, that so he might both chastise Joab for his faults, and rescue himself from the bondage in which Joab had hitherto held him.

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 [275]2Sa 20:4-10).

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.
