Leviticus 15:26

כָּל־הַמִּשְׁכָּ֞ב אֲשֶׁר־תִּשְׁכַּ֤ב עָלָיו֙ כָּל־יְמֵ֣י זוֹבָ֔הּ כְּמִשְׁכַּ֥ב נִדָּתָ֖הּ יִֽהְיֶה־לָּ֑הּ וְכָֽל־הַכְּלִי֙ אֲשֶׁ֣ר תֵּשֵׁ֣ב עָלָ֔יו טָמֵ֣א יִהְיֶ֔ה כְּטֻמְאַ֖ת נִדָּתָֽהּ׃

καὶ πᾶσαν κοίτην ἐφ’ ἢν ἂν κοιμηθῇ ἐπ’ αὐτῆς πάσας τὰς ἡμέρας τῆς ῥύσεως κατὰ τὴν κοίτην τῆς ἀφέδρου ἔσται αὐτῇ, καὶ πᾶν σκεῦος ἐφ’ ὃ ἐὰν καθίσῃ ἐπ’ αὐτὸ ἀκάθαρτον ἔσται κατὰ τὴν ἀκαθαρσίαν τῆς ἀφέδρου.

Toda cama en que durmiere todo el tiempo de su flujo, le será como la cama de su costumbre; y todo mueble sobre que se sentare, será inmundo, como la inmundicia de su costumbre.

Any bed on which she lies or any furniture on which she sits during the days of her discharge will be unclean, like her bed during her menstrual period.
