And Alma went forth, and also Amulek, among the people, to declare the words of God unto them; and they were filled with the Holy Ghost. And they had power given unto them, insomuch that they could not be confined in dungeons; neither was it possible that any man could slay them; nevertheless they did not exercise their power until they were bound in bands and cast into prison.
Now, this was done that the Lord might show forth his power in them. And it came to pass that they went forth and began to preach and to prophesy unto the people, according to the spirit and power which the Lord had given them.
