Hebrews 5:12 For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.
Hebrews 6:Intro Principles of the doctrine of Christ -- The restitution -- The surety of God's promise.
Hebrews 6:1 Therefore not leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God.
DC 1:Intro Revelation given through Joseph Smith, Jr., at a special conference held at Hiram, Portage County, Ohio, November 1, 1831. It was to serve as a preface to the "Book of Commandments." W.W. Phelps and Company began the printing of the "Book of Commandments" at Independence, Missouri, but the plant was destroyed by a mob in July 1833 before the book could be completed. The last section to be set up ended with the words, "blood of Ephraim" (D. and C. 64:7b).
When the first edition of the Doctrine and Covenants was published in 1835, it included the sections (chapters) set in type for the "Book of Commandments" and also instructions received prior to July 1833 but not included in the "Book of Commandments." To this was added further instruction received and a statement of principles approved prior to the date of publication. The preface was continued as Section 1.
If the preface had been included in the order it was received, it would have appeared immediately prior to Section 67 in recent editions.
A revelation received November 3, 1831, known as the Appendix, does not appear in the "Book of Commandments," as was originally intended, but will be found as Section 100 of the 1835 edition of the Doctrine and Covenants and as Section 108 in all subsequent editions.
DC 27:Intro SECTION 27
Revelation given to Oliver Cowdery through Joseph Smith, Jr., in September 1830 at Fayette, New York.
Hiram Page had come into possession of a stone by use of which he had obtained certain "revelations" concerning the building of Zion, church organization, and similar matters. Oliver Cowdery and the Whitmer family, to whom Hiram was related, tended to accept his claims. The instruction now received appoints Oliver to an important mission and then sets forth the associated principles of prophetic guidance and common consent according to the church covenants and the prayer of faith. It should be noted that Oliver, who had shared responsibility for the difficulties which had arisen, is now commanded to take responsibility for their settlement.

DC 48:Intro SECTION 48
Revelation given through Joseph Smith, Jr., March 8, 1831, at Kirtland, Ohio. This is addressed to the Saints in Kirtland who needed guidance concerning the manner of locating members of the church arriving from the East (D. and C. 45:12). They were uncertain about the advisability of purchasing land in view of the projected move farther west, and about the Zionic principles on which lands should be allocated.

Revelation given through Joseph Smith, Jr., to Edward Partridge at Kirtland, Ohio, May 1831.

Edward Partridge was the only bishop in the church at this time.
