Mosiah 23:1

Now Alma, having been warned of the Lord that the armies of king Noah would come upon them, and had made it known to his people, therefore they gathered together their flocks, and took of their grain, and departed into the wilderness before the armies of king Noah.

The Lord warned Alma that King Noah’s armies would come after them. Alma told his people about this. So they gathered their animals and food. Then they went into the wilderness before King Noah’s armies came.

The Lord warned Alma that King Noah’s armies were coming for them. Alma told his people right away. They rounded up their flocks, grabbed what grain they could carry, and fled into the wilderness before Noah’s soldiers arrived.
