וְאִם־תֵּרָאֶ֨ה ע֜וֹד בַּ֠בֶּגֶד אֽוֹ־בַשְּׁתִ֤י אֽוֹ־בָעֵ֙רֶב֙ א֣וֹ בְכָל־כְּלִי־ע֔וֹר פֹּרַ֖חַת הִ֑וא בָּאֵ֣שׁ תִּשְׂרְפֶ֔נּוּ אֵ֥ת אֲשֶׁר־בּ֖וֹ הַנָּֽגַע׃
And if it appear still in the garment, or in the warp, or in the woof, or in any thing of skin, it is breaking out, thou shalt burn that wherein the plague is with fire.
Targum Jonathan on Leviticus
But if it reappear in the garment, or in the warp or woof, or in anything of skin, and maketh increase, thou shalt burn such material which hath the plague in it.
