 Mark chapter 9, he says this, and if your hand causes you to stumble, stumble, cut it off. For it is better for you to enter life crippled than to having two hands to go into hell, into the unquenchable fire where their worm does not die and their fire is not quenched. It's the unquenchable fire. He also called it eternal fire. He called it the furnace of fire. He called it the lake of fire.
