Joseph begins his stay in Liberty jail, which lasts almost six months. The jail is 22 feet square, with walls four feet thick. The food is filthy, and at one time the guards boast that they have fed the prisoners human flesh. At another point the prisoners are fed poison. However, some exciting things also occur during their prison stay. Parley P. Pratt writes poetry and a history of his life; Lyman Wight is blessed several times by Joseph and learns many things "yet unknown to the Church." George A. Smith is called to the apostleship; Brigham Young and others receive instructions about moving the Saints to Illinois; Joseph reveals several of the most important sections of the D&C.
