Divers weights, and divers measures, both of them are alike abomination to the LORD.
– Proverbs 20:10
The law requires equity and justice in business (Leviticus 19:35-26; Deuteronomy 25:13-16). Unequal weights and measures here refers to cheating the transaction by a false weight. This could be a way of oppressing the poor and inviting Divine retribution (Proverbs 17:5). The word for abomination means loathsome, or detestable. God hates all such cheating. The standard of measure belongs to the Lord (Proverbs 16:11) and proverbs such as this one show God’s sovereign omniscience. He ponders the hearts and judges by his standard.
