Can I reckon someone to be pure who uses dishonest balances,
and with a bag of deceptive weights? Bible

“dishonest balances.” It is not that there was more than one balance, but the noun “balance” is a dual noun because there were two pans or pouches, one on each end of the balance beam. Unscrupulous merchants often kept stones of different weight in their bag that only they could easily tell apart. That allowed them to buy more of something but sell less of something, and thus they cheated in their business dealings (Lev. 19:35; Deut. 25:13-16). [For more on the biblical balance, see commentary on Prov. 11:1].
