D&C 10. Part 6. Verses 42-70.

Part 5 is here.

The earliest text for verses 1-41 of D&C 10 is the Book of Commandments. However, an earlier copy of verses 42-70 is found in Revelation Book 1 (the Book of Commandments and Revelations ms published in the opening volume of the Joseph Smith Papers’ Revelations and Translations series). The RB 1 dates this entry to April 1829. But there may be reasons to think of it as somewhat later than this.
