In the Bible, the maintenance of honest weights and measures was an important principle in the life of an Israelite. God himself directly commanded his people to be honest when they traded and not attempt to cheat each other (especially those who were strangers).
The stranger that dwells with you shall be to you as one born among you, and you shall love him as yourself . . . You shall do no unrighteousness in judgment, in measures and weights, or in quantity. You shall have just balances, just weights, a just ephah, and a just hin . . . (Leviticus 19:34 - 36, Holy Bible Faithful Version).
Wise King Solomon also taught that maintaining honest standards of trade was critical to the success of God's people. Using different sized weights and measures, for the purpose of cheating others, was an abomination to the Eternal (Proverbs 20:10, 23). The Bible states that greedy merchants were known to use undersized measures when selling commodities like grain. They also would weigh a buyer's money using extra heavy weights so that they could steal even more gold or silver (Amos 8:4 - 5).
