13 Yet the Lord testified against Israel and against Judah, by all of His prophets, every seer, saying, "Turn from your evil ways, and keep My commandments and My statutes, according to all the law which I commanded your fathers, and which I sent to you by My servants the prophets." 14 Nevertheless they would not hear, but stiffened their necks, like the necks of their fathers, who did not believe in the Lord their God. 15 And they rejected His statutes and His covenant that He had made with their fathers, and His testimonies which He had testified against them; they followed idols, became idolaters, and went after the nations who were all around them, concerning whom the Lord had charged them that they should not do like them. 16 So they left all the commandments of the Lord their God, made for themselves a molded image and two calves, made a wooden image and worshiped all the host of heaven, and served Baal. 17 And they caused their sons and daughters to pass through the fire, practiced witchcraft and soothsaying, and sold themselves to do evil in the sight of the Lord, to provoke Him to anger. 18 Therefore the Lord was very angry with Israel, and removed them from His sight; there was none left but the tribe of Judah alone.

Commentary on 2 Kings 17:7-23
(Read 2 Kings 17:7-23)
Though the destruction of the kingdom of the ten tribes was but briefly related, it is in these verses largely commented upon, and the reasons of it given. It was destruction from the Almighty: the Assyrian was but the rod of his anger, Isaiah 10:5. Those that bring sin into a country or family, bring a plague into it, and will have to answer for all the mischief that follows. And vast as the outward wickedness of the world is, the secret sins, evil thoughts, desires, and purposes of mankind are much greater. There are outward sins which are marked by infamy; but ingratitude, neglect, and enmity to God, and the idolatry and impiety which proceed therefrom, are far more malignant. Without turning from every evil way, and keeping God's statutes, there can be no true godliness; but this must spring from belief of his testimony, as to wrath against all ungodliness and unrighteousness, and his mercy in Christ Jesus.
