[July 12, 1843. Wednesday.] This A.M. I wrote a Revelation consisting of 10 pages on the order of the priesthood, showing the designs in Moses, Abraham, David and Solomon having many wives and concubines &c. After it was wrote Presidents Joseph and Hyrum presented it and read it to E[mma] who said she did not believe a word of it and appeared very rebellious. Joseph told me to Deed all the unincumbered lots to E[mma] and the children. He appears much troubled about E[mma].
