pass that after they had bound me, insomuch that I
could not move, the compass, which had been prepared of the Lord,
did cease to work; wherefore, they knew not whither they should
steer the ship, insomuch that there arose a great storm, yea, a
great and terrible tempest, and we were driven back upon the waters
for the space of three days; and they began to be frightened
exceedingly, lest they should be drowned in the sea; nevertheless
they did not loose me. And on the fourth day, which we had been
driven back, the tempest began to be exceeding sore. And it came to
pass that we were about to be swallowed up in the depths of the sea.

Then they untied him.

And it came to pass after they had loosed me, behold, I took the
compass, and it did work whither I desired it. And it came to pass
that I prayed unto the Lord; and after I had prayed, the winds did
cease, and the storm did cease, and there was a great calm.

Equipped with their compass, these ancients appear to have had the
advantage of Noah.

Their voyage was toward a "promised land"--the only name they give it.
They reached it in safety.

Polygamy is a recent feature in the Mormon religion, and was added by
Brigham Young after Joseph Smith's death. Before that, it was regarded
as an "abomination." This verse from the Mormon Bible occurs in Chapter
II. of the book of Jacob:

For behold, thus saith the Lord, this people begin to wax in
iniquity; they understand not the Scriptures; for they seek to
excuse themselves in committing whoredoms, because of the things
which were written concerning David, and Solomon his son. Behold,
David and Solomon truly had many wives and concubines, which thing
was abominable before me, saith the Lord; wherefore, thus saith the
Lord, I have led this people forth out of the land of Jerusalem, by
the power of mine arm, that I might raise up unto me a righteous
branch from the fruit of the loins of Joseph. Wherefore, I the Lord
God, will no suffer that this people shall do like unto them of old.

However, the project failed--or at least the modern Mormon end of it--for
Brigham "suffers" it. This verse is from the same chapter:

Behold, the Lamanites your brethren, whom ye hate, because of their
filthiness and the cursings which hath come upon their skins, are
more right
