וַיְדַבֵּר יְהֹוָה אֶל־מֹשֶׁה לֵּאמֹר׃ Hashem spoke to Moshe, saying: וְהַדָּוָה בְּנִדָּתָהּ וְהַזָּב אֶת־זוֹבוֹ לַזָּכָר וְלַנְּקֵבָה וּלְאִישׁ אֲשֶׁר יִשְׁכַּב עִם־טְמֵאָה׃ and concerning her who is in menstrual infirmity, and concerning anyone, male or female, who has a discharge, and concerning a man who lies with an unclean woman.
