25:13-16 Dishonest gain always brings a curse on men'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 of the Lord.But thou shall have a perfect and just weight, a perfect and just measure shall thou have,.... That is, full weights, and full measures; and such as are alike, and everywhere used, according to the standard of the country; See Gill on Leviticus 19:36,

that thy days may be lengthened in the land which the Lord thy God giveth thee; long life was always reckoned a blessing, and is frequently promised to, obedience, and particularly long life in the land of Canaan; which was a most delightful and fruitful land, and which a man might wish to live long in; deceitful men, are threatened with not living half their days, and such may they be said to be that use false weights and measures, Psalm 55:23.
