Deuteronomy 25:13-16

AKJV(i) 13 You shall not have in your bag divers weights, a great and a small. 14 You shall not have in your house divers measures, a great and a small. 15 But you shall have a perfect and just weight, a perfect and just measure shall you have: that your days may be lengthened in the land which the LORD your God gives you. 16 For all that do such things, and all that do unrighteously, are an abomination to the LORD your God.
