Alma 30:44 44 But Alma said unto him:  Thou hast had signs enough; will ye tempt your God?  Will ye say, Show unto me a sign, when ye have the testimony of all these thy brethren, and also all the holy prophets?  The scriptures are laid before thee, yea, and all things denote there is a God; yea, even the earth, and all things that are upon the face of it, yea, and its motion, yea, and also all the planets which move in their regular form do witness that there is a Supreme Creator.

Alma 30:45 45 And yet do ye go about, leading away the hearts of this
people, testifying unto them there is no God?  And yet will ye
deny against all these witnesses?  And he said:  Yea, I will deny,
except ye shall show me a sign.

Alma 30:46 46 And now it came to pass that Alma said unto him:  Behold, I am
grieved because of the hardness of your heart, yea, that ye will
still resist the spirit of the truth, that thy soul may be
destroyed.

Alma 30:47 47 But behold, it is better that thy soul should be lost than that thou shouldst be the means of bringing many souls down to destruction, by thy lying and by thy flattering words; therefore if thou shalt deny again, behold God shall smite thee, that thou shalt become dumb, that thou shalt never open thy mouth any more, that thou shalt not deceive this people any more.

Alma 30:48 48 Now Korihor said unto him:  I do not deny the existence of a
God, but I do not believe that there is a God; and I say also,
that ye do not know that there is a God; and except ye show me a
sign, I will not believe.

Alma 30:49 49 Now Alma said unto him:  This will I give unto thee for a
sign, that thou shalt be struck dumb, according to my words; and
I say, that in the name of God, ye shall be struck dumb, that ye
shall no more have utterance.

Alma 30:50 50 Now when Alma had said these words, Korihor was struck dumb,
that he could not have utterance, according to the words of Alma.

Alma 30:51 51 And now when the chief judge saw this, he put forth his hand and wrote unto Korihor, saying:  Art thou convinced of the power of God?  In whom did ye desire that Alma should show forth his sign?  Would ye that he should afflict others, to show unto thee a sign?  Behold, he has showed unto you a sign; and now will ye dispute more?

Alma 30:52 52 And Korihor put forth his hand and wrote, saying:  I know that
I am dumb, for I cannot speak; and I know that nothing save it
were the power of God could bring this upon me; yea, and I always
knew that there was a God.

Alma 30:53 53 But behold, the devil hath deceived me; for he appeared unto me in the form of an angel, and said unto me:  Go and reclaim this people, for they have all gone astray after an unknown God.  And he said unto me:  There is no God; yea, and he taught me that which I should say.  And I have taught his words; and I taught them because they were pleasing unto the carnal mind; and I taught them, even until I had much success, insomuch that I verily believed that they were true; and for this cause I withstood the truth, even until I have brought this great curse upon me.
