Once the Church of Jesus Christ was organized, Joseph's brothers Hyrum and Samuel and their father, together with Oliver Cowdery and Joseph Knight, were “anxious to know of the Lord what might be their respective duties, in relation to this work.” Joseph's history says, “I enquired of the Lord and received for them the following.”[1]

In section 23, the Lord speaks to each of these men in turn, offering blessings and warnings, prophecies and promises. Note especially the conditions on which the prophesied blessings depend.

Oliver Cowdery pridefully withdrew from the church in 1838 and remained out for a decade before returning humbly. During that period he wrote defensively about his importance in the Restoration. Afterward, Oliver testified meekly of the Book of Mormon and of receiving the priesthood from ministering angels along with Joseph Smith.[2] When Oliver was aware of pride and made his calling known, the Lord opened his heart to preach the truth.

For Hyrum, verse 3 fulfills the Lord’s promise to him in section 11. There the Lord told Hyrum Smith that if he would learn the word of the Lord, then his tongue would be loosed to preach it. Hyrum must have studied the scriptures in the year between the two revelations, since section 23 announces that his tongue is loosed. Hyrum preached powerfully ever after. Joseph's father and brother Samuel also became effective missionaries and church leaders in response to this revelation.

Joseph Knight had done so much for Joseph—provided money, paper for the Book of Mormon, food, transportation, and moral support. He was most comfortable behind the scenes. What section 23 commanded was more difficult for him: to join the church meant to preach the gospel. Father Knight wrote that he wrestled with the decision to be baptized but finally decided not to. A few weeks later, he and his wife chose to be baptized.
