"'You shall do no unrighteousness in judgment, in measures of length, of weight, or of quantity.
You shall not have in your bag diverse weights, a great and a small.
Honest balances and scales are Yahweh's; all the weights in the bag are his work.
Hear this, you who desire to swallow up the needy, and cause the poor of the land to fail,
Shall I be pure with dishonest scales, and with a bag of deceitful weights?
