'Cannot' in the Bible

saying, What shall we do to these men? for that indeed a notable miracle hath been wrought through them, is manifest to all that dwell in Jerusalem; and we cannot deny it.

for we cannot but speak the things which we saw and heard.

And certain men came down from Judaea and taught the brethren,'saying , Except ye be circumcised after the custom of Moses, ye cannot be saved.

Seeing then that these things cannot be gainsaid, ye ought to be quiet, and to do nothing rash.

Paul said to the centurion and to the soldiers, Except these abide in the ship, ye cannot be saved.
