Leviticus 18:15
Swete's Septuagint · Berean Standard Bible
συγγενὴς γάρ σού ἐστιν. ἀσχημοσύνην νύμφης σου οὐκ ἀποκαλύψεις· γυνὴ γὰρ υἱοῦ σού ἐστιν, οὐκ ἀποκαλύψεις τὴν ἀσχημοσύνην αὐτῆς.
You must not have sexual relations with your daughter-in-law. She is your son’s wife; you are not to have sexual relations with her.
