'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).
