18 God was so thoroughly angry that he got rid of them, got them out of the country for good until only one tribe was left - Judah. 19 (Judah, actually, wasn't much better, for Judah also failed to keep God's commands, falling into the same way of life that Israel had adopted.) 20 God rejected everyone connected with Israel, made life hard for them, and permitted anyone with a mind to exploit them to do so. And then this final No as he threw them out of his sight. 21 Back at the time that God ripped Israel out of their place in the family of David, they had made Jeroboam son of Nebat king. Jeroboam debauched Israel - turned them away from serving God and led them into a life of total sin. 22 The children of Israel went along with all the sins that Jeroboam did, never murmured so much as a word of protest. 23 In the end, God spoke a final No to Israel and turned his back on them. He had given them fair warning, and plenty of time, through the preaching of all his servants the prophets. Then he exiled Israel from her land to Assyria. And that's where they are now.

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.
