Alma 22:1 And now it came to pass that Moroni did not stop making preparations for war - or to defend themselves against the Lamanites. For he caused that his armies should commence - in the commencement of the twentieth year of the reign of the judges - That they should commence in
digging up heaps of earth round about all the cities throughout all the land which was possessed by the Nephites.
Alma 24:54 And Teancum, by the orders of Moroni, caused that they should commence in laboring in
digging a ditch round about the Land or the City Bountiful.
