Give a portion of their substance

1. Alma 27: 24
     24 And now behold, this will we do unto our brethren, that they may inherit the land Jershon; and we will guard them from their enemies with our armies, on condition that they will give us a portion of their substance to assist us that we may maintain our armies.
2. Alma 43: 13
     13 And the people of Ammon did give unto the Nephites a large portion of their substance to support their armies; and thus the Nephites were compelled, alone, to withstand against the Lamanites, who were a compound of Laman and Lemuel, and the sons of Ishmael, and all those who had dissented from the Nephites, who were Amalekites and Zoramites, and the descendants of the priests of Noah.
