Leviticus 18:11
Swete's Septuagint · Berean Standard Bible
ἀσχημοσύνην θυγατρὸς γυναικὸς πατρός σου οὐκ ἀποκαλύψεις· ὁμοπατρία ἀδελφή σού ἐστιν, οὐκ ἀποκαλύψεις τὴν ἀσχημοσύνην αὐτῆς.
You must not have sexual relations with the daughter of your father’s wife, born to your father; she is your sister.
