'Perish' in the Bible

For God so loved the world, that he gave his only begotten Son, that whosoever believeth on him should not perish, but have eternal life.

and I give unto them eternal life; and they shall never perish, and no one shall snatch them out of my hand.

nor do ye take account that it is expedient for you that one man should die for the people, and that the whole nation perish not.
