'Unmarried' in the Bible

The girl was very beautiful, a virgin and unmarried; and she went down to the spring and filled her jar and came up.

And in that day seven women will take hold of one man, saying, “We will eat our own food and wear [and provide] our own clothes; only let us be called by your name; take away our shame [of being unmarried].”

Therefore the Lord Himself will give you a sign: Listen carefully, the virgin will conceive and give birth to a son, and she will call his name Immanuel (God with us).

Now as to the matters of which you wrote: It is good (beneficial, advantageous) for a man not to touch a woman [outside marriage].

But I say to the unmarried and to the widows, [that as a practical matter] it is good if they remain [single and entirely devoted to the Lord] as I am.

But I want you to be free from concern. The unmarried man is concerned about the things of the Lord, how he may please the Lord;

and his interests are divided. The unmarried woman or the virgin is concerned about the matters of the Lord, how to be holy and set apart both in body and in spirit; but a married woman is concerned about worldly things, how she may please her husband.
