He is a merchant - Or, indignantly, "a merchant in whose hands are the balances of deceit!" How could they love "mercy and justice," whose trade was "deceit," who weighed out deceit with their goods? False in their dealings, in their weights and measures, and, by taking advantage of the necessities of others, oppressive also. Deceit is the sin of weakness oppression is the abuse of power. Wealth does not give the power to use naked violence but wealthy covetousness manifoldly grinds the poor. When for instance, wages are paid in necessaries priced exorbitantly, or when artisans are required to buy at a loss at their masters' shops, what is it but the union of deceit and oppression? The trading world is full of oppression, scarcely veiled by deceit. "He loveth to oppress." Deceit and oppression have, each, a devilish attractiveness to those practiced in them; deceit, as exercising cleverness, cunning, skill in overreaching, outwitting; oppression, as indulging self will, caprice, love of power, insolence, and the like vices. The word "merchant," as the prophet spoke it, was "Canaan;" merchants being so called, because the Canaanites or Phoenicians were the then great merchant-people, as astrologers were called Chaldeans. The Phoenicians were, in Homer's time, infamous for their griping in traffic. They are called "gnawers" and "money-lovers" . To call Israel, "Canaan," was to deny to him any title to the name of Israel, "reversing the blessing of Jacob, so that, as it had been said of Jacob, "thy name shall be called no more Jacob, but Israel," he would in fact say, 'Thy name shall be called no more Israel, but Canaan'; as being, through their deeds, heirs, not to the blessings of Israel but to the curse of Canaan." So Ezekiel saith, "Thy father was an Amorite, and thy mother a Hittite" Ezekiel 16:3.

He is a merchant - Or a Canaanite; referring to the Phoenicians, famous for their traffic. Ephraim is as corrupt as those heathenish traffickers were. He kept, as many in all ages have done, a weight and a weight; a heavy one to buy with and a light one to sell by.

[He is] (g) a merchant, the balances of deceit [are] in his hand: he loveth to oppress.
(g) As for Ephraim, he is more like the wicked Canaanites than godly Abraham or Jacob.

He is a merchant,.... Here is a change of person from "thou" to "he", from Judah to Ephraim, who is said to be a "merchant"; and if that was all, there is nothing worthy of dispraise in it; but he was a cheating merchant, a fraudulent dealer, as appears by what follows: or he is Canaan, or a Canaanite (y); more like a descendant of Canaan, by his manners, than a descendant of Jacob. But the Canaanites dealing much in merchandise, their name became a common name for a merchant, as a Chaldean for an astrologer; and as the children of Israel possessed their land, so they followed the same business and employment of life; which, had they performed honestly, would not have been to their discredit; but they were too much like the Canaanites, of whom Philostratus (z) says, they were covetous and fraudulent; and this was Ephraim's character. The Targum is,
"be you not as merchants;''
the balances of deceit are in his hand; he used false weights and measures; made the ephah small, and the shekel great, and falsified the balances by deceit; had wicked balances, and deceitful weights, and the scant measure, which is abominable, Amos 8:5; they pretended to weigh everything exactly they bought or sold; but cheated either by sleight or hand, holding the balances as they should not; or had one pair of scales and weights to buy with, and another to sell by, contrary to the law of God, Leviticus 19:35;
he loveth to oppress; instead of keeping and doing mercy and justice, they oppressed the poor, ground their faces, defrauded them of their due, and by secret and private methods cheated them in their dealings with them, and brought them to poverty and distress; and this they took delight and pleasure in, which showed a want of a principle of honesty in them, and that they were habituated to such a course of life, and were hardened in it, and had no remorse of conscience for it, but rather gloried in it.

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.

merchant--a play on the double sense of the Hebrew, "Canaan," that is, a Canaanite and a "merchant" Ezekiel 16:3 : "Thy birth is . . . of Canaan." They who naturally were descendants of pious Jacob had become virtually Canaanites, who were proverbial as cheating merchants (compare Isaiah 23:11, Margin), the greatest reproach to Israel, who despised Canaan. The Phœnicians called themselves Canaanites or merchants (Isaiah 23:8).
oppress--open violence: as the "balances of deceit" imply fraud.

"Canaan, in his hand is the scale of cheating: he loves to oppress. Hosea 12:8. And Ephraim says, Yet I have become rich, have acquired property: all my exertions bring me no wrong, which would be sin." Israel is not a Jacob who wrestles with God; but it has become Canaan, seeking its advantage in deceit and wrong. Israel is called Canaan here, not so much on account of its attachment to Canaanitish idolatry (cf. Ezekiel 16:3), as according to the appellative meaning of the word Kena‛an, which is borrowed from the commercial habits of the Canaanites (Phoenicians), viz., merchant or trader (Isaiah 23:8; Job 40:30), because, like a fraudulent merchant, it strove to become great by oppression and cheating; not "because it acted towards God like a fraudulent merchant, offering Him false show for true reverence," as Schmieder supposes. For however thoroughly this may apply to the worship of the Israelites, it is not to this that the prophet refers, but to fraudulent weights, and the love of oppression or violence. And this points not to their attitude towards God, but to their conduct towards their fellow-men, which is the very opposite of what, according to the previous verse, the Lord requires (chesed ūmishpât), and the very thing which He has forbidden in the law, in Leviticus 19:36; Deuteronomy 24:13-16, and also in the case of ‛âshaq, violence, in Leviticus 6:2-4; Deuteronomy 24:14. Ephraim prides itself upon this unrighteousness, in the idea that it has thereby acquired wealth and riches, and with the still greater self-deception, that with all its acquisition of property it has committed no wrong that was sin, i.e., that would be followed by punishment. און does not mean "might" here, but wealth, opes, although as a matter of fact, since Ephraim says this as a nation, the riches and power of the state are intended. כּל־יגיעי is not written at the head absolutely, in the sense of "so far as what I have acquired is concerned, men find no injustice in this;" for it that were the case, בּי would stand for לי; but it is really the subject, and יצמצאוּ is to be taken in the sense of acquiring = bringing in (cf. Leviticus 5:7; Leviticus 12:8, etc.).

A merchant - Ephraim is so far from being as Jacob, that you may account him a Canaanite, a subtle merchant.
