In the year 1844, a short time before the death of the Prophet Joseph Smith, it was my privilege to attend a regular prayer circle meeting in the upper room over the Prophet's store. There were present at this meeting most of the Twelve Apostles, their wives, and a number of other prominent brethren and their wives. On that occasion the Prophet arose and spoke at great length, and during his remarks I heard him say that he had conferred on the heads of the Twelve Apostles all the keys and powers pertaining to the Priesthood, and that upon the heads of the Twelve Apostles the burden of the kingdom rested, and they would have to carry it."[5] BENJAMIN F. JOHNSON'S TESTIMONY. At the eighty-seventh birthday anniversary celebration of Elder Benjamin F. Johnson, held at Mesa, Arizona, July 29, 1905, that Patriarch said: "I speak of things of which I know I was the business partner of Joseph Smith, from my mission until the time of his martyrdom, was as familiar with him as with my brother or my father. "Do I know that Brigham Young was the true successor of Joseph Smith? I knew it before the Prophet was martyred, for Joseph had made it known. I was present when the Prophet gave his charge to the Twelve Apostles, when in council, after solemn prayer, he rose up with the light of heaven shining in his countenance, related his experiences with reference to the beginning of this work, the responsibilities placed upon him, the persecutions and hardships through which he had passed. He declared that God had revealed all the truth necessary to save mankind, had given unto him the keys of the kingdom, and he had carried the weight and load thus far, and then, speaking directly to the Twelve, he said: 'I now roll off the burden of this responsibility upon you; I give unto you all the keys and powers bestowed upon me, and I say unto you, that unless you round up your shoulders and bear off this kingdom you will be damned."
