الأمثال ٢٠:١٠

This proverb passes sentence of condemnation against gross sins in action and life. Diverse stones, diverse measures - An abomination to Jahve are they both. The stones are, as at Pro 11:1; Pro 16:11, those used as weights. Stone and stone, ephah and ephah, means that they are of diverse kinds, one large and one small (the lxx, in which the sequence of the proverbs from Pro 20:10 is different, has μέγα καὶ μικρόν), so that one may be able deceitfully to substitute the one for the other. איפה (from אפה, to bake) may originally have been used to designate such a quantity of meal as supplied a family of moderate wants; it corresponds to the bath (Eze 45:11) as a measure for fluids, and stands here synecdochically instead of all the measures, including, e.g., the cor, of which the ephah was a tenth part, and the seah, which was a third part of it. 10b = Pro 17:5, an echo of Lev 19:36; Deu 25:13-16. Just and equal measure is the demand of a holy God; the contrary is to Him an abhorrence.

See here, 1. The various arts of deceiving that men have, all which evils the love of money is the root of. In paying and receiving money, which was then commonly done by the scale, they had divers weights, an under-weight for what they paid and an over-weight for what they received; in delivering out and taking in goods they had divers measures, a scanty measure to sell by and a large measure to buy by. This was done wrong with plot and contrivance, and under colour of doing right. Under these is included all manner of fraud and deceit in commerce and trade. 2. The displeasure of God against them. Whether they be about the money or the goods, in the buyer or in the seller, they are all alike an abomination to the Lord. He will not prosper the trade that is thus driven, nor bless what is thus got. He hates those that thus break the common faith by which justice is maintained, and will be the avenger of all such.

20:10 False weights and unequal measures: Merchants, for example, should not cheat their customers by using false weights to weigh out grain (cp. 11:1; 16:11; 20:23).
