'Perish' in the Bible

So the shipmaster came to him, and said unto him, What meanest thou, O sleeper? arise, call upon thy God, if so be that God will think upon us, that we perish not.

Wherefore they cried unto Jehovah, and said, We beseech thee, O Jehovah, we beseech thee, let us not perish for this man's life, and lay not upon us innocent blood; for thou, O Jehovah, hast done as it pleased thee.

Who knoweth whether God will not turn and repent, and turn away from his fierce anger, that we perish not?
