SEV Biblia, Chapter 11:21 Y oyendo Adad en Egipto que David había dormido con sus padres, y que era muerto Joab general del ejército, Adad dijo a Faraón: Déjame ir a mi tierra.
John Gill's Bible Commentary Ver. 21. And when Hadad heard in Egypt that David slept with his fathers , etc.] 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.
Matthew Henry Commentary Verses 14-25 - While Solomon kept close to God and to his duty, there was no enemy to give him uneasiness; but here we have an account of two. If against us he can make us fear even the least, and the very grasshopper shall be burden. Though they were moved by principles of ambition or revenge God used them to correct Solomon.
