Sometime between 1 March and 4 May 1835, JS prepared an instruction on the nature of the Melchizedek Priesthood, describing its relation to the “Aaronic” or “Levitical” lesser priesthood and to the offices within these divisions of priesthood. (Instruction on Priesthood, between ca. 1 Mar. and ca. 4 May 1835 [D&C 107].)
See Exodus 33:11.
A September 1832 revelation stated that after the children of Israel fell away, God “took Moses out of there midst and the holy Priesthood also, and the lesser Priesthood continued, which Priesthood holdeth the keys of the ministring of Angels.” (Revelation, 22–23 Sept. 1832 [D&C 84:25–26].)
