v1-3: The sin of pride. Scripture everywhere commends humility. But Ephraim (Israel) spoke from a position of pride, exalting himself. No wonder ‘he died.’ Contrast James 1.19, be slow to speak
Again, the folly of idolatry. They are the works of men's hands, made by human design, ingenuity and skill. They will pass away, like nothing.
v4-5: See 12.9-10; although the people departed from God, He remains the Lord their God. Although they are guilty of 'spiritual adultery,' His claim on His people remains.
Bringing them out of Egypt, He commanded, "You shall have no other God but me;" indicating His jealousy, and His demand of loyalty.
v6: Prosperity brought rebellion; when things go well, people forget God. We must beware complacency, Deut 32.15; 2 Chr 26.15-16. When we attribute our 'success' to our own efforts, we are beginning on the route to idolatry and self-glorification.
v7-8: The certainty of judgment; and the severity and unpleasantness of it. Israel is about to suffer deeply.
v9-10: Deliverance is only from the Lord, none other can save. But Israel fails to cast herself upon the Lord.
v11: See 1 Sam 8-12; the children of Israel sought a king to be their deliverer. Many kings later, they have gone from bad to worse, see 9.15. With or without a king, the people rebelled against God.
v12-13: Israel's guilt remains, her sins of each generation.
v14: Ultimately, God has power and victory over death. In Him is eternal salvation; such things remain true of God whatever the rebellion of His people.
v15-16: The people bear their guilt, with all the suffering that that meant.
