Deuteronomy 25:13 - 25:16
13 “You shall not have in your bag differing weights, a large and a small. 14 You shall not have in your house differing measures, a large and a small. 15 You shall have a full and just weight; you shall have a full and just measure, that your days may be prolonged in the land which Yahweh your God gives you. 16 For everyone who does these things, everyone who acts unjustly, is an abomination to Yahweh your God.
