וְכֹ֣ל אֲשֶׁר־יִפֹּל־עָלָיו֩ מֵהֶ֨ם ׀ בְּמֹתָ֜ם יִטְמָ֗א מִכָּל־כְּלִי־עֵץ֙ א֣וֹ בֶ֤גֶד אוֹ־עוֹר֙ א֣וֹ שָׂ֔ק כָּל־כְּלִ֕י אֲשֶׁר־יֵעָשֶׂ֥ה מְלָאכָ֖ה בָּהֶ֑ם בַּמַּ֧יִם יוּבָ֛א וְטָמֵ֥א עַד־הָעֶ֖רֶב וְטָהֵֽר׃
And upon whatsoever any of them, when they are dead, doth fall, it shall be unclean; whether it be any vessel of wood, or raiment, or skin, or sack, whatsoever vessel it be, wherewith any work is done, it must be put into water, and it shall be unclean until the even; then shall it be clean.
Mishnah Kelim
One who touches the upper beam, the lower beam, the harnesses, the sley, the thread that is drawn over purple material, or a spool which is not to be shot back, remains clean. If he touches the woof, the standing warp, the double thread that is drawn over purple material or a spool which is to be shot back, he becomes unclean. If one touches the wool that is on the distaff, or on the spool, he remains clean. If he touches the spinner: Before it was uncovered he is unclean, After it was uncovered he remains clean.
