Bereshit 24:16

בתולה A VIRGIN — from the place of her hymen. ואיש לא ידעה AND A MAN DID NOT KNOW HER — not in its way (meaning, anally). Because the daughters of the nations would guard the place of their hymens, but abandon themselves from another place. It testifies about this one that she was clean from all [of this] (Genesis Rabbah 60:5).

And the girl was very fair to look upon, a virgin, neither had any man known her: and she went down to the well, and filled her pitcher, and came up.

וְהַֽנַּעֲרָ֗ טֹבַ֤ת מַרְאֶה֙ מְאֹ֔ד בְּתוּלָ֕ה וְאִ֖ישׁ לֹ֣א יְדָעָ֑הּ וַתֵּ֣רֶד הָעַ֔יְנָה וַתְּמַלֵּ֥א כַדָּ֖הּ וַתָּֽעַל׃
