Leviticus 14:43 Halakhah

וְאִם־יָשׁ֤וּב הַנֶּ֙גַע֙ וּפָרַ֣ח בַּבַּ֔יִת אַחַ֖ר חִלֵּ֣ץ אֶת־הָאֲבָנִ֑ים וְאַחֲרֵ֛י הִקְצ֥וֹת אֶת־הַבַּ֖יִת וְאַחֲרֵ֥י הִטּֽוֹחַ׃

And if the plague come again, and break out in the house, after that the stones have been taken out, and after the house hath been scraped, and after it is plastered;
