withhold their labor from me, for God had commanded me that I
should build a ship.

1 Nephi 17:50
50 And I said unto them: If God had commanded me to do all
things I could do them. If he should command me that I should
say unto this water, be thou earth, it should be earth; and if I
should say it, it would be done.

1 Nephi 17:51
51 And now, if the Lord has such great power, and has wrought so
many miracles among the children of men, how is it that he cannot
instruct me, that I should build a ship?

1 Nephi 17:52
52 And it came to pass that I, Nephi, said many things unto my
brethren, insomuch that they were confounded and could not
contend against me; neither durst they lay their hands upon me
nor touch me with their fingers, even for the space of many days.

Now they durst not do this lest they should wither before me, so
powerful was the Spirit of God; and thus it had wrought upon
them.

1 Nephi 17:53
53 And it came to pass that the Lord said unto me: Stretch forth
thine hand again unto thy brethren, and they shall not wither
before thee, but I will shock them, saith the Lord, and this will
I do, that they may know that I am the Lord their God.
