'Eternal' in the Bible

“If your hand or your foot causes you to stumble, cut it off and throw it from you; it is better for you to enter life crippled or lame, than to have two hands or two feet and be cast into the eternal fire.

And someone came to Him and said, “Teacher, what good thing shall I do that I may obtain eternal life?”

And everyone who has left houses or brothers or sisters or father or mother or children or farms for My name’s sake, will receive many times as much, and will inherit eternal life.

“Then He will also say to those on His left, ‘Depart from Me, accursed ones, into the eternal fire which has been prepared for the devil and his angels;

These will go away into eternal punishment, but the righteous into eternal life.”
