Idolatry and filthiness

1. Enos 1: 20
   20 And I bear record that the people of Nephi did seek diligently to restore the Lamanites unto the true faith in God. But our labors were vain; their hatred was fixed, and they were led by their evil nature that they became wild, and ferocious, and a blood-thirsty people, full of idolatry and filthiness; feeding upon beasts of prey; dwelling in tents, and wandering about in the wilderness with a short skin girdle about their loins and their heads shaven; and their skill was in the bow, and in the cimeter, and the ax. And many of them did eat nothing save it was raw meat; and they were continually seeking to destroy us.
2. Morm. 5: 15
   15 And also that the seed of this people may more fully believe his gospel, which shall go forth unto them from the Gentiles; for this people shall be scattered, and shall become a dark, a filthy, and a loathsome people, beyond the description of that which ever hath been amongst us, yea, even that which hath been among the Lamanites, and this because of their unbelief and idolatry.
