"By their brethren"

1. Mosiah 10: 12
     12 They were a wild, and ferocious, and a blood-thirsty people, believing in the tradition of their fathers, which is this—Believing that they were driven out of the land of Jerusalem because of the iniquities of their fathers, and that they were wronged in the wilderness by their brethren, and they were also wronged while crossing the sea;
2. Alma 16: 8
     8 And they came upon the armies of the Lamanites, and the Lamanites were scattered and driven into the wilderness; and they took their brethren who had been taken captive by the Lamanites, and there was not one soul of them had been lost that were taken captive. And they were brought by their brethren to possess their own lands.
3. Alma 27: 29
     29 Therefore, they would suffer death in the most aggravating and distressing manner which could be inflicted by their brethren, before they would take the sword or cimeter to smite them.
4. Alma 32: 3
     3 Therefore they were not permitted to enter into their synagogues to worship God, being esteemed as filthiness; therefore they were poor; yea, they were esteemed by their brethren as dross; therefore they were poor as to things of the world; and also they were poor in heart.
