Twenty yeers old] By this account, Ahaz was but eleven yeers old when his son Hezekiah was born; for he reigned but sixteen yeers: and Hezekiah was five and twenty yeers old when he began to reign, chap. 18. v. 2. Some refer the relative particle, he, to Jotham, as if it had been thus expressed; Twenty yeers old was Ahaz, when Jotham began to reign. See 2 Chron. 36. 9.
