1 Kings 16:34 - Albert Barnes' Notes on the Bible

This seems to be adduced as a proof of the general impiety of Ahab’s time. The curse of Joshua against the man who should rebuild Jericho had hitherto been believed and respected. But now faith in the old religion had so decayed, that Joshua’s malediction had lost its power. Hiel, a Bethelite of wealth and station, undertook to restore the long-ruined fortress. But he suffered for his temerity. In exact accordance with the words of Joshua’s curse, he lost his firstborn son when he began to lay anew the foundations of the walls, and his youngest when he completed his work by setting up the gates. We need not suppose that Jericho had been absolutely uninhabited up to this time. But it was a ruined and desolate place without the necessary protection of walls, and containing probably but few houses (Judges 3:13 note). Hiel re-established it as a city, and it soon became once more a place of some importance 2 Chronicles 28:15.
