And it came to pass that I beheld the spirit of God, that it wrought upon other Gentiles; and they went forth out of captivity, upon the many waters.
And it came to pass that I beheld many multitudes of the Gentiles, upon the land of promise; and I beheld the wrath of God, that it was upon the seed of my brethren; and they were scattered before the Gentiles, and they were smitten. And I beheld the spirit of the Lord, that it was upon the Gentiles; that they did prosper, and obtain the land of their inheritance; and I beheld that they were white, and exceeding fair and beautiful, like unto my people, before that they were slain.
And it came to pass that I, Nephi, beheld that the Gentiles which had gone forth out of captivity, did humble themselves before the Lord; and the power of the Lord was with them; and I beheld that their mother Gentiles was gathered together upon the waters, and upon the land also, to battle against them; and I beheld that the power of God was with them; and also, that the wrath of God was upon them, that were gathered together against them to battle. And I, Nephi, beheld that the Gentiles which had gone out of captivity, were delivered by the power of God, out of the hands of all other nations.
