Albert Barnes Commentary Proverbs 11:1

"A false balance is an abomination to Jehovah; But a just weight is his delight." — Proverbs 11:1 (ASV)

This emphatic reproduction of the old rule of Deuteronomy 25:13-14 is perhaps a trace of the danger of dishonesty associated with the growing commerce of the Israelites. The stress laid upon the same sin in Proverbs 16:11 and Proverbs 20:10 testifies to the desire of the teacher to educate the youth of Israel to a high standard of integrity, just as the protest of Hosea against it (Hosea 12:7) shows the zeal of the prophet in rebuking what was becoming more and more a besetting sin.

A just weight—literally, as in the margin—indicates a time when stones rather than metal were used as a standard of weight. Compare Deuteronomy 25:13.
