21 When Hadad heard in Egypt that David slept with his fathers, and that Joab the captain of the army was dead, Hadad said to Pharaoh, "Let me depart, that I may go to my own country."

That Hadad should wait for the death of Joab before requesting leave to return to Idumaea shows how terrible an impression had been made by the severe measures which that commander had carried out twenty-five or thirty years previously 1-Kings 11:16. The inability of refugees to depart from an Oriental court without the king's leave, and his unwillingness ordinarily to grant leave, are illustrated by many passages in the history of Persia.
And when Hadad heard in Egypt that David slept with his fathers,.... Was dead and buried, as the death of princes is soon known in other countries, and especially a king of such fame as David:
and that Joab the captain of the host was dead: whose name might be terrible to Hadad, because of the slaughter of men he had made in his country:
Hadad said unto Pharaoh, let me depart, that I may go to mine own country; with a view and an hope to recover it, now David and Joab were dead.
Joab - Whom he feared as much as David himself. Own country - Whither accordingly he came; and was there, even from the beginning of Solomon's reign. And it is probable, by the near relation which was between his wife and Solomon's; and, by Pharaoh's intercession, he obtained his kingdom with condition of subjection and tribute to be paid by him to Solomon; which condition he kept 'till Solomon fell from God, and then began to be troublesome, and dangerous to his house and kingdom.
