13You shall not have in your bag diverse weights, a great and a small. 14You shall not have in your house diverse measures, a great and a small. 15A perfect and just weight shall you have; a perfect and just measure shall you have: that your days may be long in the land which Yahweh your God gives you. 16For all who do such things, [even] all who do unrighteously, are an abomination to Yahweh your God.
