'Better' in the Bible

But if they don't have self-control, let them marry. For it's better to marry than to burn.

So then both he who gives his own virgin in marriage does well, and he who doesn't give her in marriage does better.

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

But in giving you this command, I don't praise you, that you come together not for the better but for the worse.
