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.
