God expects his people to use accurate weights and measures, and to use just balances. This is underlined in the Law, the Prophets and the wisdom literature.
The law demanded honesty in using weights and measures
Leviticus 19:35-36Cheating by falsifying weights and measures was common in a culture where there was no standardisation or regulatory authority.See alsoDeuteronomy 25:13-16
The prophets called for the right use of weights and measures
