Deuteronomy 25:13-19

13Never carry two sets of weights, a heavier one and a lighter one.

14Never have two kinds of measures in your house, a larger one and a smaller one.

15Use accurate and honest weights and measures. Then you will live for a long time in the land that the Lord your God is giving you.

16Everyone who uses dishonest weights and measures is disgusting to the Lord.

17Remember what the Amalekites did to you on your trip from Egypt.

18They attacked you when you were tired and exhausted and killed all those who were lagging behind. They weren’t afraid of God.

19So when the Lord your God gives you peace from all your enemies around you in the land that he is giving you as your own property, don’t forget to erase every memory of the Amalekites from the earth.
