Alma 27:24

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 conditions that they will give us a portion of their substance to assist us, that we may maintain our armies.

“We will do this for our relatives so they can own the land Jershon. We will keep them safe from their enemies with our armies. But they must give us some of their things to help us. That way we can take care of our armies.”

“Here’s what we’ll do: we’ll give them the land of Jershon as their inheritance, and we’ll defend them with our armies. In return, they’ll contribute part of their resources to help us maintain those armies.”
