Wayyiqra (Leviticus) 16:27, 30

“And the bull for the sin offering and the goat for the sin offering, whose blood was brought in to make atonement in the Set-apart Place, is brought outside the camp. And they shall burn their skins, and their flesh, and their dung with fire.

“For on that day he makes atonement for you, to cleanse you, to be clean from all your sins before יהוה.
