Jesus Christ taught the descendants of Lehi in the Americas (who were of the house of Israel) many of the same gospel principles He taught to His Jewish disciples in the Old World. The teachings as recorded in the book of Matthew, found in the New Testament, known as the Sermon on the Mount (Matthew 5) were again taught by the Savior when he visited Lehi’s descendants.
The passages below show the words from verses 27 and 30 of the King James version of Matthew and the comparable verses from 3 Nephi in the Book of Mormon.
“Ye have heard that it was said of them of old time, Thou shalt not commit adultery: But I say unto you, That whosoever looketh upon a woman to lust after her hath committed adultery with her already in his heart. And if thy right eye offend thee, pluck it out, and cast it from thee; for it is profitable for thee that one of thy members should perish, and not that they whole body should be cast into hell. And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.” (Matthew 5:27-30)
“Behold, it is written by them of old time, that thou shalt not commit adultery; But I say unto you, that whosoever looketh on a woman, to lust after her, hath committed adultery already in his heart. Behold, I give unto you a commandment, that ye suffer none of these things to enter into your heart; For it is better that ye should deny yourselves of these things, wherein ye will take up your cross, than that ye should be cast into hell.” (3 Nephi 12:27-30)
Questions:
-Why did Christ not mention dismemberment to the descendants of Lehi when teaching of the evils of adultery (as he did when teaching the Jews in the Old World)?
