'Better' in the Bible

But if they have not continency, let them marry: for it is better to marry than to burn.

So then both he that giveth his own virgin daughter in marriage doeth well; and he that giveth her not in marriage shall do better.

But food will not commend us to God: neither, if we eat not, are we the worse; nor, if we eat, are we the better.

But in giving you this charge, I praise you not, that ye come together not for the better but for the worse.
