Mosiah 28: 1

Mosiah 27:32 And now it came to pass that Alma began from this time forward to teach the people, and those who were with Alma at the time the angel appeared unto them, traveling round about through all the land, publishing to all the people the things which they had heard and seen, and preaching the word of God in much tribulation, being greatly persecuted by those who were unbelievers, being smitten by many of them.  34 And four of them were the sons of Mosiah; and their names were Ammon, and Aaron, and Omner, and Himni; these were the names of the sons of Mosiah.
