Many murders and sins which we have committed

1. Alma 24: 9-11
     9 And behold, I also thank my God, that by opening this correspondence we have been convinced of our sins, and of the many murders which we have committed.
     10 And I also thank my God, yea, my great God, that he hath granted unto us that we might repent of these things, and also that he hath forgiven us of those our many sins and murders which we have committed, and taken away the guilt from our hearts, through the merits of his Son.
     11 And now behold, my brethren, since it has been all that we could do, (as we were the most lost of all mankind) to repent of all our sins and the many murders which we have committed, and to get God to take them away from our hearts, for it was all we could do to repent sufficiently before God that he would take away our stain—
2. Alma 27: 8
     8 And the king said unto him: Yea, if the Lord saith unto us go, we will go down unto our brethren, and we will be their slaves until we repair unto them the many murders and sins which we have committed against them.
