Context
11 When 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:
12 Then thou shalt cut off her hand, thine eye shall not pity her.
13 Thou shalt not have in thy bag divers weights, a great and a small.
