Important Message Regarding This Lesson

The Daily Mitzvah schedule runs parallel to the daily study of 3 chapters of Maimonides' 14-volume code. There are instances when the Mitzvah is repeated a few days consecutively while the exploration of the same Mitzvah continues in the in-depth track.

Positive Commandment 109 (Digest)
Immersing in a Mikvah (Ritual Pool)

"He shall bathe all his body in water"Leviticus 15:16.

A person who chooses to become cleansed of any ritual impurity is commanded to immerse in a mikvah [a natural pool of water]. According to the tradition of the Oral Law, for a mikvah to be kosher it must contain enough water for [an average] person to submerge himself within them—unless it is a moving stream of water, in which case even the smallest amount of water suffices [for a smaller than average individual, or for immersing a ritually impure utensil].

Some details:

  • Of all the types of ritually impure people, only the zav requires immersion in a moving stream of water.
  • This mitzvah is not obligatory. As long as an individual has no intention of entering the Temple Mount, he may remain in his ritually impure state.
  • An individual's purification process is not finalized until the sun sets on the day he immerses.
  • There may not be anything separating between the person's body and the waters of the mikvah.

The wolf shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together, and a little child shall lead them. And the cow and the bear shall feed, their young ones shall lie down together; and the lion shall eat straw like the ox. And the suckling child shall play on the hole of the cobra, and the weaned child shall put his hand on the viper's nest. They shall not hurt nor destroying all my holy mountain; for the earth shall be filled with the knowledge of G-d, as the waters cover the sea
