'Unmarried' in the Bible

See now, I have two unmarried daughters; I will send them out to you so that you may do to them whatever seems good to you: only do nothing to these men, for this is why they have come under the shade of my roof.

But I say to the unmarried and to the widows, It is good for them to be even as I am.

(Or if she goes away from him, let her keep unmarried, or be united to her husband again); and that the husband may not go away from his wife.

If you get married it is not a sin; and if an unmarried woman gets married it is not a sin. But those who do so will have trouble in the flesh. But I will not be hard on you.

But it is my desire for you to be free from cares. The unmarried man gives his mind to the things of the Lord, how he may give pleasure to the Lord:

So then, he who gets married to his virgin does well, and he who keeps her unmarried does better.
