D&C 132
The Lord instructed the saints - 
"...I reveal unto you a new and an everlasting covenant; and if ye abide not that covenant, then are ye damned; for no one can reject this covenant and be permitted to enter into my glory."  (Doctrine and Covenants | Section 132:4)
In my opinion, "the new and everlasting covenant" includes all laws and covenants.  But in this case the Lord introduces "a new and everlasting covenant" that in my mind is a law and part of the overall covenant.  Obviously, this new and everlasting covenant spoken herein is celestial marriage or marriage for time and all eternity.
