Leviticus 19:35-37

ISV(i) 35 “You are not to act unjustly in deciding a case or when measuring weight and quantity. 36 You are to maintain just balances and reliable standards for weights, dry volumes, and liquid volumes. I am the LORD your God, who brought you out of the land of Egypt. 37 Observe all my statutes and all my ordinances in order to practice them. I am the LORD.”
