Between these dates Joseph writes a long letter to Bishop Edward Partridge in particular and the Saints in general. Parts of the letter are later extracted and form what is now D&C 121, 122, and 123. Besides these sections, the letter also encourages the Saints to have love, fellowship, and compassion on the orphans and the widows; expresses thanks for the letters he (the Prophet) has received; explains the reasons why the Lord tries his Saints; warns the Saints against pride; encourages the Saints to become friends with Isaac Galland; encourages abiding the law.
[He prophecies that "not many years hence ... [his enemies] and their posterity shall be swept from under heaven, saith God, that not one of them is left to stand by the wall". D&C 121:11]
