Leviticus 16:8 – Then Aaron must throw lots for the two goats. One lot will be for the Lord and the other for Azazel.
One for Yahweh. One for Azazel.
Azazel: entire removal (of sin). Azazel is often used to refer to a fallen angel also, but in this context it is the origination of the word, “scapegoat.” A goat that was let go. Though it is possible it’s one that actually takes the blame.
