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 after his Resurrection.
The passages below show the words from verses 33 and 37 of the King James version of Matthew and the comparable verses from 3 Nephi in the Book of Mormon.
“Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths. But I say unto you, Swear not at all; neither by heaven; for it is God’s throne: Nor by the earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King. Neither shalt thou swear by thy head, because thou canst not make one hair white or black. But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.” (Matthew 5:33-37)
“And again it is written, thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths; But verily, verily, I say unto you, swear not at all; neither by heaven, for it is God’s throne; Nor by the earth, for it is his footstool. Neither shalt thou swear by thy head, because thou canst not make one hair black or white; But let your communication be Yea, yea; Nay, nay; for whatsoever cometh of more than these is evil.” (3 Nephi 12:33-37)
-What is the Lord communicating when He teaches us to limit our commitments with others to a simple “yes” or “no”?
-While He teaches His followers not to engage in oaths, is there any question that He expects a person’s word to be upheld by their actions?
