'Eternal Fire' in the Bible

And if thy hand or thy foot causes thee to stumble, cut them off and cast from thee. It is good for thee to enter into life crippled or maimed, than having two hands or two feet to be cast into the eternal fire.

Then he will also say to those at the left hand, Depart from me, ye accursed, into the eternal fire prepared for the devil and his agents.

As Sodom and Gomorrah, and the cities around them, the same kind of way with these who indulged in fornication, and who went rear of queer flesh, are set forth an example, undergoing the punishment of eternal fire.
