The words Jesus Christ spoke to Joseph Smith are called revelations. Some of these revelations were published in the Book of Commandments. While this book was being printed, people became angry with the Church members who had moved to their town. They threw the printing press into the street. Two sisters named Mary Elizabeth and Caroline Rollins gathered as many pages of the Book of Commandments as they could. They ran into a cornfield to hide from the angry men, and Heavenly Father kept them safe. The revelations in the Book of Commandments later became part of the Doctrine and Covenants.
