Jacob 7:13 13 And it came to pass that he said unto me:  Show me a sign by
this power of the Holy Ghost, in the which ye know so much.

Jacob 7:14 14 And I said unto him:  What am I that I should tempt God to
show unto thee a sign in the thing which thou knowest to be true?

Yet thou wilt deny it, because thou art of the devil.  Nevertheless, not my will be done; but if God shall smite thee, let that be a sign unto thee that he has power, both in heaven and in earth; and also, that Christ shall come.  And thy will, O Lord, be done, and not mine.

Jacob 7:15 15 And it came to pass that when I, Jacob, had spoken these
words, the power of the Lord came upon him, insomuch that he fell
to the earth.  And it came to pass that he was nourished for the
space of many days.

Jacob 7:16 16 And it came to pass that he said unto the people:  Gather
together on the morrow, for I shall die; wherefore, I desire to
speak unto the people before I shall die.

Jacob 7:17 17 And it came to pass that on the morrow the multitude were
gathered together; and he spake plainly unto them and denied the
things which he had taught them, and confessed the Christ, and
the power of the Holy Ghost, and the ministering of angels.

Jacob 7:18 18 And he spake plainly unto them, that he had been deceived by
the power of the devil.  And he spake of hell, and of eternity,
and of eternal punishment.

Jacob 7:19 19 And he said:  I fear lest I have committed the unpardonable
sin, for I have lied unto God; for I denied the Christ, and said
that I believed the scriptures; and they truly testify of him. 
And because I have thus lied unto God I greatly fear lest my case
shall be awful; but I confess unto God.

Jacob 7:20 20 And it came to pass that when he had said these words he
could say no more, and he gave up the ghost.

Jacob 7:21 21 And when the multitude had witnessed that he spake these
things as he was about to give up the ghost, they were astonished
exceedingly; insomuch that the power of God came down upon them,
and they were overcome that they fell to the earth.

Jacob 7:22 22 Now, this thing was pleasing unto me, Jacob, for I had
requested it of my Father who was in heaven; for he had heard my
cry and answered my prayer.

Jacob 7:23 23 And it came to pass that peace and the love of God was
restored again among the people; and they searched the
scriptures, and hearkened no more to the words of this wicked
man.

Jacob 7:24 24 And it came to pass that many means were devised to reclaim and restore the Lamanites to the knowledge of the truth; but it all was vain, for they delighted in wars and bloodshed, and they had an eternal hatred against us, their brethren.  And they sought by the power of their arms to destroy us continually.

Jacob 7:25 25 Wherefore, the people of Nephi did fortify against them with
their arms, and with all their might, trusting in the God and
rock of their salvation; wherefore, they became as yet,
conquerors of their enemies.
