'Unmarried' in the Bible

But I say to the unmarried and to widows, It is good for them if they abide even as I.

(but should she depart, let her remain unmarried, or else be reconciled to her husband); and that the husband leave not his wife.

But I would have you to be free from cares. He that is unmarried is careful for the things of the Lord, how he may please the Lord:

and is divided.'so also the woman that is unmarried and the virgin is careful for the things of the Lord, that she may be holy both in body and in spirit: but she that is married is careful for the things of the world, how she may please her husband.
