DC 16:Intro SECTION 16
Although Martin Harris is not mentioned in this revelation given in June 1829, at Fayette, he joined Oliver Cowdery and David Whitmer in selecting the first apostles in the Quorum of Twelve in the Restoration. The selection was made at Kirtland, February 14, 1835. Those chosen were ordained under the hands of Oliver, David, and Martin (the Three Witnesses), each praying separately.
DC 55:2a And again, you shall be ordained to assist my servant Oliver Cowdery to do the work of printing, and of selecting, and writing books for schools, in this church, that little children also may receive instruction before me as is pleasing unto me.
DC 69:2b nevertheless, let my servant John Whitmer travel many times from place to place, and from church to church, that he may the more easily obtain knowledge--preaching and expounding, writing, copying, selecting, and obtaining all things which shall be for the good of the church, and for the rising generations, that shall grow up on the land of Zion, to possess it from generation to generation, for ever and ever. Amen.
DC 120:10b In making these selections the presidents of Seventy should confer with the several quorums before so selecting, and be guided by wisdom and the spirit of revelation, choosing none but men of good repute.
DC 125:13e and also selecting and ordaining a high priest to act in the office of bishop, carrying with him the authority of the conference.
DC 132:Intro SECTION 132
President Joseph Smith died at Independence, Missouri, December 10, 1914. His oldest living son, Frederick Madison Smith, had been designated as his successor and was accepted by the church in this capacity. He was set apart as President of the Church and the High Priesthood at the Stone Church in Independence on May 5, 1915.
The Conference of 1915 had given consideration to the honorable release of Presiding Bishop E. L. Kelley, but referred any necessary action to the Presidency and Council of Twelve. President F. M. Smith reported the situation to a council of the Presidency, Council of Twelve, and Presiding Bishopric. By action of this council the text of the revelation was taken from the body of President F. M. Smith's report and presented to the General Conference, where it was endorsed and approved for inclusion in the Doctrine and Covenants.
The matter of selecting one to succeed Bishop E.L. Kelley in the office of Presiding Bishop has received by me careful and prayerful consideration.
DC 143:3a The voice of inspiration to me also is as follows: It is wisdom for the church to accept the direction of the council of Presidents of Seventy and complete their organization. My servants of this council should not be overcareful in selecting elders, under the law, to occupy as Seventies.
