Unequal weights are an abomination to Yahweh,
and deceitful scales are not good. Bible

“Unequal weights .” Unscrupulous merchants often kept stones of different weight in their bag 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].

“are not good.” This is the figure of speech, tapeinosis, “understatement.” False scales are not just “not good,” like unequal weights they are an abomination to God.
