Alma 14:10 – 11
.
10  And it came to pass that when Amulek saw the pains of the women and children which were consuming in the fire, he was also pained; and he saith unto Alma: How can we witness this awful scene?  Therefore let us stretch forth our hands, and exercise the power of God which is in us, and save them from the flames.
11  But Alma saith unto him:  The Spirit constraineth me that I must not stretch forth mine hand; for behold the Lord receiveth them up unto himself, in glory; and he doth suffer that they may do this thing, or that the people may do this thing unto them, according to the hardness of their hearts, that the judgments which he shall exercise upon them in his wrath may be just; and the blood of the innocent shall stand as a witness against them, yea, and cry mightily against them at the last day.
