2 Samuel 20:22

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 Ecclesiastes 9:7 . 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.
