-- 1829 mid-Apr.
[Oliver Cowdery] Joseph Smith, Jr. (at Harmony, Susquehanna, PA) claimed to receive a message from God directed to Oliver Cowdery (LDS D&C Sec. 9). Cowdery was told in the text that God said "... it is not expedient that you should translate at this present time." Apparently Cowdery had begun to "translate" some part of the "golden plates" or some supplemental record associated with them and had thus disregarded his primary work "to write for my servant Joseph."

[Oliver Cowdery] Joseph Smith, Jr. (at Harmony, Susquehanna, PA) claimed to receive a message from God directed to himself (LDS D&C Sec. 10). Smith was told that the material in the lost 116 pages of the supposedly ancient record could be replaced, more or less, by his translating "the plates of Nephi" which would "throw greater views upon my gospel." (1)
[Oliver Cowdery] Oliver Cowdery wrote a letter to David Whitmer, in Fayette, Seneca, NY, relating his experiences in working with Joseph Smith, Jr. Cowdery confessed to Whitmer that Joseph seemed to know "his secret thoughts, and all he had meditated upon before going to see him..." It is possible that some intimate confidant of Oliver's revealed some of his secrets to Smith during this period. Between late Apr. and early June Sidney Rigdon's whereabouts were unaccounted for, except that Lyman Wight claimed to have been baptized by Rigdon in OH some time during May. (1)
