עֶרְוַ֨ת בַּת־אֵ֤שֶׁת אָבִ֙יךָ֙ מוֹלֶ֣דֶת אָבִ֔יךָ אֲחוֹתְךָ֖ הִ֑וא לֹ֥א תְגַלֶּ֖ה עֶרְוָתָֽהּ׃ (ס)
The nakedness of thy father’s wife’s daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.
Targum Jonathan on Leviticus
The nakedness of thy father's wife's daughter, who hath been begotten of thy father, she is thy sister, thou shalt not dishonour.
