Matthew Poole and continuators on 1 Kings 11:21

21 And when Hadad heard in Egypt that David slept with his fathers, and that Joab the captain of the host was dead, Hadad said to Pharaoh, Let me depart, that I may go to mine own countrey .

Whom he feared as much as David himself.

Whether accordingly he came; and was there, even from the beginning of Solomon's Reign; where he either lived as a private person, yet secretly working for the recovery of his Crown when an opportunity was offered; or rather, by the near relation which was between his Wife and Solomons, 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 it seems he began to be troublesome to him, and dangerous to his House and Kingdom.
