Albert Barnes Commentary Proverbs 20:10

"Diverse weights, and diverse measures, Both of them alike are an abomination to Jehovah." — Proverbs 20:10 (ASV)

See (Proverbs 11:1): Here perhaps, as a companion to (Proverbs 20:9), with a wider application to all judging a person by rules that we do not apply to ourselves or to another.
