I thought it was awesome to get this from a faithful gal of Lamanitish background who posted this scripture. Kind of clear as day, if you ask me:
2 O all ye that are pure in heart, lift up your heads and receive the pleasing word of God, and feast upon his love; for ye may, if your minds are firm, forever.
3 But, wo, wo, unto you that are not pure in heart, that are filthy this day before God; for except ye repent the land is cursed for your sakes; and the Lamanites, which are not filthy like unto you, nevertheless they are cursed with a sore cursing, shall scourge you even unto destruction.
4 And the time speedily cometh, that except ye repent they shall possess the land of your inheritance, and the Lord God will lead away the righteous out from among you.
5 Behold, the Lamanites your brethren, whom ye hate because of their filthiness and the cursing which hath come upon their skins, are more righteous than you; for they have not forgotten the commandment of the Lord, which was given unto our father—that they should have save it were one wife, and concubines they should have none, and there should not be whoredoms committed among them.
6 And now, this commandment they observe to keep; wherefore, because of this observance, in keeping this commandment, the Lord God will not destroy them, but will be merciful unto them; and one day they shall become a blessed people.
7 Behold, their husbands love their wives, and their wives love their husbands; and their husbands and their wives love their children; and their unbelief and their hatred towards you is because of the iniquity of their fathers; wherefore, how much better are you than they, in the sight of your great Creator?
This is specifically foreshadowing what will happen when a remnant goes among the unrighteous Gentiles and tears to pieces.
16 Then shall ye, who are a aremnant of the house of Jacob, go forth among them; and ye shall be in the midst of them who shall be many; and ye shall be among them as a lion among the beasts of the forest, and as a young blion among the flocks of sheep, who, if he goeth through both ctreadeth down and teareth in pieces, and none can deliver.
