13 You shall not keep two differing weights in your bag, one heavy and the other light;
14 nor shall you keep two different ephahs in your house, one large and the other small.
15 But use a full and just weight, a full and just ephah, so that you may have a long life on the land the Lord, your God, is giving you.
16 For everyone who does these things, everyone who does what is dishonest, is an abomination to the Lord, your God.
17 Bear in mind what Amalek did to you on the journey after you left Egypt,
18 how he surprised you along the way, weak and weary as you were, and struck down at the rear all those who lagged behind; he did not fear God.
19 Therefore, when the Lord, your God, gives you rest from all your enemies round about in the land which the Lord, your God, is giving you to possess as a heritage, you shall blot out the memory of Amalek from under the heavens. Do not forget!
