70 And there we did place our armies that we might stop the armies of the Lamanites, that they might not get possession of any of our lands; Therefore, we did fortify against them with all our force.
71 And it came to pass that in the three hundred and sixty and first year, the Lamanites did come down to the City of Desolation to battle against us; And it came to pass that in that year we did beat them insomuch that they did return to their own lands again.
72 And in the three hundred and sixty and second year, they did come down again to battle;
73 And we did beat them again and did slay a great number of them, And their dead were cast into the sea.
74 And now because of this great thing which my people the Nephites had done, They began to boast in their own strength and began to swear before the heavens that they would avenge themselves of the blood of their brethren which had been slain by their enemies;
75 And they did swear by the heavens, and also by the throne of God, that they would go up to battle against their enemies and would cut them off from the face of the land.
76 And it came to pass that I, Mormon, did utterly refuse from this time forth to be a commander and a leader of this people because of their wickedness and abomination.
77 Behold, I had led them - notwithstanding their wickedness - I had led them many times to battle, And I had loved them according to the love of God which was in me with all my heart;
78 And my soul had been poured out in prayer unto my God all the day long for them; Nevertheless, it was without faith because of the hardness of their hearts.
79 And thrice have I delivered them out of the hands of their enemies and they have repented not of their sins;
80 And when they had sworn by all that had been forbidden them by our Lord and Savior Jesus Christ that they would go up unto their enemies to battle and avenge themselves of the blood of their brethren, Behold, the voice of the Lord came unto me, saying: "Vengeance is Mine and I will repay! And because this people repented not after that I had delivered them, Behold, they shall be cut off from the face of the earth!"
