That Hadad fled
 While Joab was burying the slain: 
 he and certain Edomites of his father's servants with him;
 who either was a king, and these some of his officers and courtiers; or however was of the royal family, and had an equipage, and these some of them: 
 to go into Egypt;
 that was their view at first setting out, where they might hope for help, at least shelter: 
 Hadad being yet a little child;
 whom his father's servants hid, while Joab was making the slaughter he did, and took the opportunity of fleeing with him while he was burying the dead.
