'Eternal' in the Bible

If your hand or your foot causes you to stumble, cut it off, and cast it from you. It is better for you to enter into life maimed or crippled, rather than having two hands or two feet to be cast into the eternal fire.

Everyone who has left houses, or brothers, or sisters, or father, or mother, or wife, or children, or lands, for my name's sake, will receive one hundred times, and will inherit eternal life.

Then he will say also to those on the left hand, 'Depart from me, you cursed, into the eternal fire which is prepared for the devil and his angels;

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