Matthew Henry Commentary Deuteronomy 25:13-16

"Thou shalt not have in thy bag diverse weights, a great and a small. Thou shalt not have in thy house diverse measures, a great and a small. A perfect and just weight shalt thou have; a perfect and just measure shalt thou have: that thy days may be long in the land which Jehovah thy God giveth thee. For all that do such things, [even] all that do unrighteously, are an abomination unto Jehovah thy God." — Deuteronomy 25:13-16 (ASV)

Dishonest gain always brings a curse on people's property, families, and souls. Happy those who judge themselves, repent of and forsake their sins, and put away evil things, that they may not be condemned by the Lord.
