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.
