Helaman 11:25

And they did commit murder and plunder; and then they would retreat back into the mountains, and into the wilderness and secret places, hiding themselves that they could not be discovered, receiving daily an addition to their numbers, inasmuch as there were dissenters that went forth unto them;

They murdered people and stole things. Then they would run back to the mountains. They hid in the wild places and secret spots. No one could find them. More people joined them every day. Nephites who left their people would go to them.

They murdered and robbed, then retreated into the mountains, wilderness, and hidden places where they couldn’t be found. Their numbers grew daily as more defectors joined them.
