Levítico 19, 36-23

Just balances, just weights, a just ephah, and a just hin, shall ye have: I am the LORD your God, which brought you out of the land of Egypt. But 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. A just weight and balance are the LORD's: all the weights of the bag are his work. Divers weights, and divers measures, both of them are alike abomination to the LORD. Divers weights are an abomination unto the LORD; and a false balance is not good.
