'Purification' in the Bible

She shall continue in the blood of purification thirty-three days. She shall not touch any holy thing, nor come into the sanctuary, until the days of her purifying are completed.

But if she bears a female child, then she shall be unclean two weeks, as in her period; and she shall continue in the blood of purification sixty-six days.

"'When the days of her purification are completed, for a son, or for a daughter, she shall bring to the priest at the door of the Tent of Meeting, a year old lamb for a burnt offering, and a young pigeon, or a turtledove, for a sin offering:

who sets his heart to seek God, Yahweh, the God of his fathers, even if they aren't clean according to the purification of the sanctuary."

They performed the duty of their God, and the duty of the purification, and [so did] the singers and the porters, according to the commandment of David, and of Solomon his son.

Each young woman's turn came to go in to King Ahasuerus after her purification for twelve months (for so were the days of their purification accomplished, six months with oil of myrrh, and six months with sweet fragrances and with preparations for beautifying women).
