Alma 26

As Ammon glories in the opportunity to be and instrument in the hands of God, we sense a bit of prejudice in his day among the Nephites as he explains -

"...do ye remember, my brethren, that we said unto our brethren in the land of Zarahemla, we go up to the land of Nephi, to preach unto our brethren, the Lamanites, and they laughed us to scorn?
24 For they said unto us: Do ye suppose that ye can bring the Lamanites to the knowledge of the truth? Do ye suppose that ye can convince the Lamanites of the incorrectness of the traditions of their fathers, as stiffnecked a people as they are; whose hearts delight in the shedding of blood; whose days have been spent in the grossest iniquity; whose ways have been the ways of a transgressor from the beginning? Now my brethren, ye remember that this was their language.
25 And moreover they did say: Let us take up arms against them, that we destroy them and their iniquity out of the land, lest they overrun us and destroy us."  (Alma 26:23–25)

He reminds is companions that the Lamanites are also their brethren.
