Helaman 6:24 24 And whosoever of those who belonged to their band should reveal unto the world of their wickedness and their abominations, should be tried, not according to the laws of their country, but according to the laws of their wickedness, which had been given by Gadianton and Kishkumen.

Helaman 6:25 25 Now behold, it is these secret oaths and covenants which Alma
commanded his son should not go forth unto the world, lest they
should be a means of bringing down the people unto destruction.

Helaman 6:26 26 Now behold, those secret oaths and covenants did not come
forth unto Gadianton from the records which were delivered unto
Helaman; but behold, they were put into the heart of Gadianton by
that same being who did entice our first parents to partake of
the forbidden fruit—­

Helaman 6:27 27 Yea, that same being who did plot with Cain, that if he would
murder his brother Abel it should not be known unto the world. 
And he did plot with Cain and his followers from that time forth.

Helaman 6:28 28 And also it is that same being who put it into the hearts of the people to build a tower sufficiently high that they might get to heaven.  And it was that same being who led on the people who came from that tower into this land; who spread the works of darkness and abominations over all the face of the land, until he dragged the people down to an entire destruction, and to an everlasting hell.

Helaman 6:29 29 Yea, it is that same being who put it into the heart of
Gadianton to still carry on the work of darkness, and of secret
murder; and he has brought it forth from the beginning of man
even down to this time.

Helaman 6:30 30 And behold, it is he who is the author of all sin.  And behold, he doth carry on his works of darkness and secret murder, and doth hand down their plots, and their oaths, and their covenants, and their plans of awful wickedness, from generation to generation according as he can get hold upon the hearts of the children of men.

Helaman 6:31 31 And now behold, he had got great hold upon the hearts of the Nephites; yea, insomuch that they had become exceedingly wicked; yea, the more part of them had turned out of the way of righteousness, and did trample under their feet the commandments of God, and did turn unto their own ways, and did build up unto themselves idols of their gold and their silver.

Helaman 6:32 32 And it came to pass that all these iniquities did come unto them in the space of not many years, insomuch that a more part of it had come unto them in the sixty and seventh year of the reign of the judges over the people of Nephi.

Helaman 6:33 33 And they did grow in their iniquities in the sixty and eighth
year also.

Helaman 6:34 34 And thus we see that the Nephites did begin to dwindle in
unbelief, and grow in wickedness and abominations, while the
Lamanites began to grow exceedingly in the knowledge of their
God; yea, they did begin to keep his statutes and commandments,
and to walk in truth and uprightness before him.
