אָר֗וּר שֹׁכֵב֙ עִם־אֲחֹת֔וֹ בַּת־אָבִ֖יו א֣וֹ בַת־אִמּ֑וֹ וְאָמַ֥ר כָּל־הָעָ֖ם אָמֵֽן׃ (ס)
Maldito el que se echare con su hermana, hija de su padre, ó hija de su madre. Y dirá todo el pueblo: Amén.
Leviticus
The nakedness of your sister [whether she is] your fathers daughter or your mothers daughter; whether she is born in the house, or she is born outside, you shall not uncover their nakedness.
