(22) To his tent= to his home. (Comp. 2Samuel 20:1, 2Samuel 18:17; 1Kings 12:16, &c.)

Benaiah.--In the four closing verses of this chapter there is again given a short summary of the chief men of David's reign, as if to form the conclusion of this account of his life. A similar summary has already been given in 2Samuel 8:16-18, and the changes introduced here mark a later period of the reign. It is noticeable that Joab still remains commander-in-chief. On Benaiah and the force which he commanded, see Note on 2Samuel 8:18. (See also 2Samuel 23:20-23.)

Verse 22. - In her wisdom; that is, with her wise counsel. The story in Ecclesiastes 9:13-15 probably refers to this narrative. They retired; Hebrew, they dispersed themselves each to his tent; that is, his home. This refers to Amasa's levies, who were glad to depart, and whom Joab did not want at Jerusalem. He took thither with him all those mentioned in ver. 7. Incensed as David must have been at the murder of Amasa following so quickly upon that of Absalom, yet that very act proved Joab's determination, and left the king powerless. He must have felt, too, that Joab was indispensable for the maintenance of peace and order in his dominions, and that he was at the least faithful to himself.

20:14-22 Justly is that place attacked, which dares to harbour a traitor; nor will the heart fare better which indulges rebellious lusts, that will not have Christ to reign over them. A discreet woman, by her prudent management, satisfied Joab, and yet saved the city. Wisdom is not confined to rank or sex; it consists not in deep knowledge; but in understanding how to act as matters arise, that troubles may be turned away and benefits secured. A great deal of mischief would be prevented, if contending parties would understand one another. Let both sides be undeceived. The single condition of peace is, the surrender of the traitor. It is so in God's dealing with the soul, when besieged by conviction and distress; sin is the traitor; the beloved lust is the rebel: part with that, cast away the transgression, and all shall be well. There is no peace on any other terms.Then the woman went unto all the people in her wisdom,.... Went from the wall of the city into it, and convened the principal inhabitants together, and made so wise a speech to them, and represented things in such a light, and so prudently conducted, that they unanimously agreed to her motion:

and they cut off the head of Sheba the son of Bichri, and cast it out to Joab; whose face Joab knew full well, and was satisfied it was his head that was thrown over:

and he blew a trumpet; as a sign of retreat:

and they retired from the city, every man to his tent; the army under Joab broke up the siege, and departed, every man to his own city, as the Targum:

and Joab returned unto Jerusalem unto the king; to give him an account of his success, and how the rebellion was crushed; and this gave him courage and boldness to appear before the king, which one would wonder else he should have, when he had killed his general in cold blood, the king had sent out, and without his leave had reassumed his post as general of the army; but he was a bold daring man, a man of blood, and hardened in sin, and had power in the army, and over David himself, that he could not do what he would with him, but was obliged to be silent, and overlook things, and even to reestablish him in his office, as appears by what follows.
