In Moses 7:48, Enoch is seeing a vision of his posterity who have become wicked. In the vision he hears the earth cry out, "Wo, wo is me, the mother of men; I am pained, I am weary, because of the wickedness of my children. When shall I rest, and be cleansed from the filthiness which is gone forth out of me? When will my Creator sanctify me, that I may rest, and righteousness for a season abide upon my face?"
This chapter is full of references to the Earth mourning and being agitated because of the wickedness of the children of men. It longs to be cleansed from a wickedness that is not its fault, but makes it suffer. Then Enoch sees several upcoming events related to giving the world some "rest." The first event is Noah and the flood. The flood's purpose is to wipe the wicked from the face of the earth, leaving only righteous Noah and his family to repopulate.
The interesting thing about this reference to the Earth resting and the posterity of Noah, is that Noah's name in Hebrew is very similar to the word for "rest." Noah's name is נח (pronounced Noach with a German ch sound like Bach) the word for rest is נוּחַ (nuach, the same word except the middle vowel changed from 0 to U). There is definitely a play on names here, which occurs repeatedly throughout the Old Testament. It is a very Biblical/Hebrew thing to do, but the reference to the Earth resting doesn't appear in the Biblical narrative. It is only in the Book of Moses.
The Book of Moses was written by Joseph Smith in 1830 and 1831. It was a part of the Joseph Smith translation of the book of Genesis. Later, Joseph Smith studied Hebrew, but in 1830 he was still a very young, rather uneducated, man. There is almost no way that: 1. he knew that the name Noah meant "rest" in Hebrew, and 2. he was aware that many of the names in the Old Testament were puns related to the person's life and mission. I believe the only way the name pun could have appeared in the book of Moses was through revelation. This is an strong evidence of the prophetic calling of the prophet Joseph Smith.
We learn from the book of Moses that the rest of the Earth after the flood is short lived. Noah's descendants would eventually fall into wickedness. Later, Jesus' atonement is another step to the Earth finding rest, but the Earth won't finally rest until the Lord returns and reigns on the Earth. (Moses 7:64).
