Bible Verses About Measures: The Jews not to be unjust in

Ye shall do no unrighteousness in judgment, in measures of length, of weight, or of quantity.

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.
