Jesus Christ bids Nephi to come forth before the people of Ancient America and is given power to baptize. Jesus calls the other disciples before the people and presents them as a means of sustainment.
18 And it came to pass that he spake unto Nephi (for Nephi was among the multitude) and he commanded him that he should come forth.
19 And Nephi arose and went forth, and bowed himself before the Lord and did kiss his feet.
20 And the Lord commanded him that he should arise. And he arose and stood before him.
21 And the Lord said unto him: I give unto you power that ye shall baptize this people when I am again ascended into heaven.
22 And again the Lord called others, and said unto them likewise; and he gave unto them power to baptize. And he said unto them: On this wise shall ye baptize; and there shall be no disputations among you.
