Deuteronomy 25:13-16

¹³Don''t carry around with you two weights, one heavy and the other light,

¹⁴and don''t keep two measures at hand, one large and the other small.

¹⁵Use 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.

¹⁶Dishonest weights and measures are an abomination to GOD, your God--all this corruption in business deals!
