12:7-14 Ephraim became a merchant: the word also signifies a Canaanite. They carried on trade upon Canaanitish principles, covetously and with fraud and deceit. Thus they became rich, and falsely supposed that Providence favoured them. But shameful sins shall have shameful punishments. Let them remember, not only what a mighty prince Jacob was with God, but what a servant he was to Laban. The benefits we have had from the word of God, make our sin and folly the worse, if we put any slight upon that word. We had better follow the hardest labour in poverty, than grow rich by sin. We may form a judgment of our own conduct, by comparing it with that of ancient believers in the like circumstances. Whoever despises the message of God, will perish. May we all hear his word with humble, obedient faith.

his reproach shall his Lord return unto him—Ephraim's dishonor to God in worshipping idols, God will repay to him. That God is "his Lord" by right redemption and special revelation to Ephraim only aggravates his guilt, instead of giving him hope of escape. God does not give up His claim to them as His, however they set aside His dominion.
