Alma Ch63

We are now at the concluding chapter of Alma and as Helaman is now passed away, the records pass down to a new spiritual leader. There also is many travels done by the Nephites, some go northward to spread and a group sails with Hagoth west. The the darn Lamanites attack out of nowhere but are defeated.
After Helaman died, the year 36 starts with the sacred plates being passed down to Shiblon who is a just, righteous man, he also happens to be one of the sons of Alma and Helaman's brother (v1-2). Moroni dies at the end of the 36th year, then the important events in the 37th year are when 5,400 men with families left Zarahemla to a land northward and Hagoth built a ship to explore the sea to the west (v3-5). In the 38th year, that ship returns and many more ships were built having many families set out northward never to be heard of again (v6-9).
Then in the 39th year Shiblon dies and because the last son of Alma, Corianton, left to go northward, the records were left to Helaman, the son of Helaman, with the responsibility of keeping them sacred from generation to generation (v10-13). Along with all the other Nephites leaving the land, there were dissenters that deserted to the Lamanites and started making them angry towards the Nephites again enough to come to war again (v14). Fortunately, the new military leader, Moronihah, drove them back to their own land and beat them bad which ends the 39th year (v15). And this is the end of the record of Alma, Helaman, and Shiblon (v17).
