Deuteronomy 25:13 MSG

[13] Don’t carry around with you two weights, one heavy and the other light, and don’t keep two measures at hand, one large and the other small. Use only one weight, a true and honest weight, and one measure, a true and honest measure, so that you will live a long time on the land that God, your God, is giving you. Dishonest weights and measures are an abomination to God, your God—all this corruption in business deals!
