Deuteronomy 25:13-16 KJV

11When men strive together one with another, and the wife of the one draweth near for to deliver her husband out of the hand of him that smiteth him, and putteth forth her hand, and taketh him by the secrets:

12Then thou shalt cut off her hand, thine eye shall not pity her.

13Thou shalt not have in thy bag divers weights, a great and a small.

14Thou shalt not have in thine house divers measures, a great and a small.

15But thou shalt have a perfect and just weight, a perfect and just measure shalt thou have: that thy days may be lengthened in the land which the LORD thy God giveth thee.

16For all that do such things, and all that do unrighteously, are an abomination unto the LORD thy God.

17Remember what Amalek did unto thee by the way, when ye were come forth out of Egypt;

18How he met thee by the way, and smote the hindmost of thee, even all that were feeble behind thee, when thou wast faint and weary; and he feared not God.
