Alma 21
1 Behold, now it came to pass that the people of Nephi were exceedingly rejoiced, because the Lord had again delivered them out of the hands of their enemies;
2 Therefore they gave thanks unto the Lord their God: yea, and they did fast much and pray much, and they did worship God with exceeding great joy.
3 And it came to pass in the nineteenth year of the reign of the Judges over the people of Nephi, that Alma came unto his son Helaman, and said unto him, Believest thou the words which I spake unto thee concerning those records which have been kept?
4 And Helaman said unto him, Yea, I believe.
5 And Alma said again, Believest thou in Jesus Christ, who shall come? And he said, Yea, I believe all the words which thou hast spoken.
6 And Alma said unto him again, Will ye keep my commandments? And he said, Yea, I will keep thy commandments with all my heart.
7 Then Alma said unto him, Blessed art thou: and the Lord shall prosper thee in this land.
8 But behold, I have somewhat to prophesy unto thee; but what I prophesy unto thee, ye shall not make known; yea, what I prophesy unto thee shall not be made known, even until the prophesy is fulfilled; therefore write the words which I shall say.
9 And these are the words: Behold, I perceive that this very people, the Nephites, according to the spirit of revelation which is in me, in four hundred years from the time that Jesus Christ shall manifest himself unto them, shall dwindle in unbelief;
10 Yea, and then shall they see wars and pestilences, yea, famines and bloodshed, even until the people of Nephi shall become extinct;
11 Yea, and this because they shall dwindle in unbelief, and fall into the works of darkness and lasciviousness, and all manner of iniquities;
