Proverbs 20:23 NIV says, “The LORD detests differing weights, and dishonest scales do not please him.”
These weights and scales were used in business transactions, a certain weight of silver for a basket of grain, say. If one party of the transaction had rigged his scales or weights to give a false measurement, he could cheat the other party. Compare it to the stereotype of a dishonest butcher weighing meat with his thumb on the scale. We who follow Christ must have a standard of honesty that pleases him. Our culture often winks at minor dishonesty in business dealings, or in getting an insurance settlement, or in reporting income for tax purposes. Some think it’s okay to cheat a business, the government, or a person who is wealthy because “they can afford it.” Nowhere in scripture is there an allowance to take what is not yours, even if from one who has much more. These are akin to using the dishonest scales which Proverbs says God detests. Christians are to be blameless, as businessmen, taxpayers and consumers.
