"Their own brethren"

1. Mosiah 24: 7
     7 And thus the Lamanites began to increase in riches, and began to ^atrade one with another and wax great, and began to be a cunning and a wise people, as to the wisdom of the world, yea, a very cunning people, delighting in all manner of wickedness and plunder, except it were among their own brethren.
2. Alma 9: 10
     10 And have ye forgotten so soon how many times he ^adelivered our fathers out of the hands of their enemies, and preserved them from being destroyed, even by the hands of their own brethren?
