tevilu

Tevilu, also known as tevilat kelim, is a Hebrew term that translates to "the dipping of vessels" or "the immersion of utensils." It is a ritual practice in Judaism that involves immersing newly acquired or manufactured items, particularly those made of metal, glass, or ceramic, into a mikveh, a ritual bath, to render them kosher for use in the home. This practice is rooted in Jewish law, or Halakha, and is designed to purify the objects and remove any spiritual impurities they may have acquired before coming into Jewish ownership.

The origin of tevilu can be traced back to the Torah, where it is mentioned in the context of purifying vessels that have come into contact with non-kosher substances or have been used by non-Jews. Over time, the practice has evolved and been codified in rabbinic literature, with specific guidelines on which items require immersion and the proper procedures for doing so.

The tevilu process typically involves inspecting the item for any non-kosher substances or damages, then immersing it in a mikveh that contains a minimum of 40 se'ah (a measure of volume) of naturally collected water. The item must be completely submerged for a brief moment, and it is customary to say a blessing before the immersion. Once the item is removed from the mikveh, it is considered ritually pure and ready for use in a kosher home.

Tevilu is performed by a knowledgeable individual, often a rabbi or a trained professional, who is familiar with the intricacies of Jewish law and the specific requirements for each type of item. The practice of tevilu continues to be an essential aspect of Jewish life, ensuring that the utensils and vessels used in the home adhere to the standards of kosher law.
