Vayikra 15:29-31

Orthodox Jewish Bible

²⁹ And on the yom shemini she shall take unto her two turtle doves, or two young pigeons, and bring them unto the kohen, to the entrance of the Ohel Mo’ed.

³⁰ And the kohen shall sacrifice the one for a chattat, and the other for an olah (burnt offering); and the kohen shall make kapporah for her before Hashem for the discharge of her tumah.

³¹ Thus shall ye separate the Bnei Yisroel from their tumah; that they die not in their tumah, when they defile My Mishkan that is among them.
