Helaman 6:8

And it came to pass that the Lamanites did also go whithersoever they would, whether it were among the Lamanites or among the Nephites; and thus they did have free intercourse one with another, for to buy and to sell, and to get gain, according to their desire.

The Lamanites could also go wherever they wanted, whether to Lamanite or Nephite lands. They traded freely with each other. They bought and sold things to make money as they wanted.

The Lamanites moved freely too, going wherever they pleased among both peoples. They traded openly with each other, buying and selling, doing business as they wished.
