Twenty years old... sixteen. There is no reason for concluding that "there must be an error in one of the passages" (viz. 2 Kings 16:2 and 2 Kings 18:2), for Ahaz begins in 622 and reigns till 616. As he was twenty when he began, he was born in 652, and died when thirty-six. Hezekiah begins in 617, and reigns twenty-nine years, till 588. As he was twenty-five when he began he was therefore born in 642, and died when he was fifty-four, From this it is clear that Ahaz was between ten and eleven when his son Hezekiah was born. This sounds improbable only to Western ears. But, to Eastern ears and physiological phenomena, there is nothing unusual, and nothing to justify. conclusion that the text is corrupt the usual excuse for ignorance of the facts.
