Deuteronomy 25:13-16

¹³Thou shalt not have in thy bag divers weights, a great and a small. ¹⁴Thou shalt not have in thine house divers measures, a great and a small. ¹⁵But thou shalt have a perfect and just weight, a perfect and just measure shalt thou have: that thy days may be lengthened in the land which the LORD thy God giveth thee. ¹⁶For all that do such things, and all that do unrighteously, are an abomination unto the LORD thy God.
