“Unequal weights and unequal measures.” Unscrupulous merchants often kept stones of different weight in their bag or had measuring cups of slightly different sizes that only they could easily tell apart so that they bought a lot and sold a little. But that kind of dishonest dealing is an abomination to Yahweh (Lev. 19:35; Deut. 25:13-16). [For more on trading using honest balances, see commentary on Prov. 11:1].
