The Lord Challenges the Wisest Person to Duplicate the Least of His Revelations

Doctrine and Covenants 67:6–9

6 Now, seek ye out of the Book of Commandments, even the least that is among them, and appoint him that is the most wise among you;
7 Or, if there be any among you that shall make one like unto it, then ye are justified in saying that ye do not know that they are true;
8 But if ye cannot make one like unto it, ye are under condemnation if ye do not bear record that they are true.
9 For ye know that there is no unrighteousness in them, and that which is righteous cometh down from above, from the Father of lights.

The Prophet Joseph Smith said:

“After the foregoing was received, William E. M’Lellin, as the wisest man, in his own estimation, having more learning than sense, endeavored to write a commandment like unto one of the least of the Lord’s, but failed; it was an awful responsibility to write in the name of the Lord. The Elders and all present that witnessed this vain attempt of a man to imitate the language of Jesus Christ, renewed their faith in the fulness of the gospel, and in the truth of the commandments and revelations which the Lord had given to the Church through my instrumentality; and the Elders signified a willingness to bear testimony of their truth to all the world.”

(History of the Church, 1:226.)
