15:30 Twentieth year - The meaning is, that he began his reign in the twentieth year after the beginning of Jotham's reign; or, which is the same thing, in the fourth year of Ahaz, son of Jotham.
15:8-31 This history shows Israel in confusion. Though Judah was not without troubles, yet that kingdom was happy, compared with the state of Israel. The imperfections of true believers are very different from the allowed wickedness of ungodly men. Such is human nature, such are our hearts, if left to themselves, deceitful above all things, and desperately wicked. We have reason to be thankful for restraints, for being kept out of temptation, and should beg of God to renew a right spirit within us.
