Several revelations were received by Joseph Smith and other church leaders while at the Johnson Farm. Sixteen of the sections of the Doctrine and Covenants were received. Among these revelations was section 1, the introduction and section 76, the vision of the degrees of glory. As part of section 76, Joseph Smith and Sidney Rigdon stated, "And now, after the many testimonies which have been given of (Jesus Christ), this is the testimony, last of all, which we give of him: That he lives! For we saw him, even on the right hand of God; and we heard the voice bearing record that he is the Only Begotten of the Father--." Also, Joseph Smith completed part of his revision of the Bible at the Johnson home.
On the night of 24 March 1832 Joseph and Emma Smith were caring for their adopted twins. Both of the twins were sick with the measles. While Joseph was sleeping on the trundle bed on the first floor of the Johnson home a mob of about 25 attacked Joseph and dragged him out the front door. Joseph struggled with the mob but was overcome. The mob choked him, tried to put acid in his mouth, put tar all over his body and then covered him with feathers. When Joseph got back to the house, Emma thought that the tar was blood and fainted. Joseph's friends spent the rest of the night cleaning the tar off of his body. The next day, Joseph preached a sermon to a crowd which included some of the mobbers and baptized three people. One of the twin babies, the eleven-month-old boy named Joseph Murdock Smith died four days later.
