Leviticus 15:22Meaning & Commentary from the Church Fathers

The law also includes a provision regarding a woman experiencing a flow of blood, rendering her unclean. Just as every item, bed, garment, and person that comes into contact with her or approaches her becomes unclean due to the emission of seed, so is she rendered impure. He likewise cleanses her through similar means, employing the washing with water, the offering of turtledoves, and the atonement performed by the priest. (See Lev. 15:1-15)
