Mikveh (sometimes spelled as mikvah, or either way without the ending -“h”) plural: mikva’ot or mikveh Hebrew: מִקְוֶוֹת / מ is a bath used for the purpose of ritual immersion in Judaism. 

The word “mikveh”, as used in the Hebrew Bible, literally means a “collection” – generally, a collection of water from whence the word “Baptism ” originates from.

Several biblical regulations specify that full immersion in water is required to regain ritual purity after ritually impure incidents have occurred. Most forms of impurity can be nullified (made powerless or rendered ineffective) through immersion in any natural collection of water. 

Living water has the further advantage of being able to purify even while flowing, as opposed to rainwater which must be stationary in order to purify. 

There are three that bear witness on the earth, being the Spirit, water and blood (1 John 5:8) and these three agree as one.. 

Mikveh was always applied when somebody was cleansing himself from impurity or uncleanness, but on the other hand; mikvah was also used when a person had been confronted by a great revelation of God’s truth.

As a sign of appreciation of that new revelation from God, the person washed (did a mikvah) to symbolize the washing a way of the old, and the acceptance or the entrance into the new way of living, which came as a result of that revealed information.

Before the entrance into the holy Sabbath (7th day), and the holy feasts of God, a mikvah is done. 

The mikveh (bath or pool) is designed to simplify this requirement, by providing a bathing facility that remains in ritual contact with a natural source of water.
