Deuteronomy 25:13-16

CAB(i) 13 You shall not have in your bag differing weights, a heavy and a light. 14 You shall not have in your house differing measures, a large and a small. 15 You shall have a true and just weight, and a true and just measure, that you may live long upon the land which the Lord your God gives you for an inheritance. 16 For everyone that does this is an abomination to the Lord your God, even everyone that does injustice.
