'Cannot' in the Bible

saying, What shall we do to these men? for that indeed an evident sign has come to pass through their means is manifest to all that inhabit Jerusalem, and we cannot deny it.

for as for us we cannot refrain from speaking of the things which we have seen and heard.

And certain persons, having come down from Judaea, taught the brethren, If ye shall not have been circumcised according to the custom of Moses, ye cannot be saved.

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