Joseph Smith dictates a revelation on priesthood quorums and baptism for the dead. The revelation lists Hyrum Smith as patriarch before the church president and ascribes to him joint presidency over the church. It makes provision, for the first time, for a bishopric to preside over the entire church. The revelation says concerning John Bennett: "his reward shall not fail, if he receive counsel; and for his love he shall be great, for he shall be mine if he do this, saith the Lord."
