Deuteronomy 25:13-16

13Thou shalt not have in thy bag divers weights, a great and a small.

14Thou shalt not have in thy house divers ephahs, a great and a small.

15A perfect and just weight shalt thou have; a perfect and just ephah shalt thou have; that thy days may be prolonged in the land that Jehovah thy 1God giveth thee.

16For every one that doeth such things, every one that doeth unrighteousness, is an abomination to Jehovah thy 2God.
