'Perish' in the Bible

I tell you, no; but unless you repent [change your old way of thinking, turn from your sinful ways and live changed lives], you will all likewise perish.

I tell you, no; but unless you repent [change your old way of thinking, turn from your sinful ways and live changed lives], you will all likewise perish.”

But not a hair of your head will perish.

I assure you and most solemnly say to you, this generation [those living at that definite period of time preceding the second coming] will not pass away until everything takes place.
