'Cannot' in the Bible

But if they cannot contain, let them marry: for it is better to marry than to burn.

Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord's table, and of the table of devils.

And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.

Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
