Deuteronomy 25:13-16

“You shall not have in your bag differing weights, a heavy and a light. You shall not have in your house differing measures, a large and a small. You shall have a perfect and just weight, a perfect and just measure, that your days may be lengthened in the land which the LORD your God is giving you. For all who do such things, all who behave unrighteously, are an abomination to the LORD your God.
