'Eternal Fire' in the Bible

And if your hand or your foot causes you to sin, cut it off and throw [it] from you! It is better for you to enter into life crippled or lame than, having two hands or two feet, to be thrown into the eternal fire!

Then he will also say to those on [his] left, 'Depart from me, [you] accursed ones, into the eternal fire that has been prepared for the devil and his angels!

as Sodom and Gomorrah and the towns around them indulged in sexual immorality and {pursued unnatural desire} [in] the same way as these, are exhibited as an example [by] undergoing the punishment of eternal fire.
