Mosiah 18:1 - 18:5
Mosiah 18:1 And now, it came to pass that Alma, who had fled from the servants of king Noah, repented of his sins and iniquities, and went about privately among the people, and began to teach the words of Abinadi—
Meanwhile Alma had repented of his sins and was now going about secretly teaching the words of Abinadi.
Mosiah 18:2 Yea, concerning that which was to come, and also concerning the resurrection of the dead, and the redemption of the people, which was to be brought to pass through the power, and sufferings, and death of Christ, and his resurrection and ascension into heaven.
He was teaching the same things as Abinadi such as the resurrection, the atonement which would all be brought about by the sufferings and death of Christ. Which would result in the resurrection of all mankind and ascension into heaven of the righteous.
Mosiah 18:3 And as many as would hear his word he did teach. And he taught them privately, that it might not come to the knowledge of the king. And many did believe his words.
He taught as many as would listen to him. Since he was a wanted man, he had to sneak around to teach, but he was having some success.
Mosiah 18:4 And it came to pass that as many as did believe him did go forth to a place which was called Mormon, having received its name from the king, being in the borders of the land having been infested, by times or at seasons, by wild beasts.
Alma could not hold meetings in the town so he set up a meeting place somewhere outside of town near a place that at various times lived dangerous animals. The place was called Mormon, named after the king that once ruled in that place.
Mosiah 18:5 Now, there was in Mormon a fountain of pure water, and Alma resorted thither, there being near the water a thicket of small trees, where he did hide himself in the daytime from the searches of the king.
The land of Mormon had a large spring of water and surround by trees. It was there that Alma hid during the day from the king Noah’s police.
