There are two goats in the bloody sin sacrifice/forgiveness, priestly mumbo jumbo:-
Leviticus 16:15:- Then shall he kill the goat of the sin offering, that is for the people, and bring his blood within the veil, and do with that blood as he did with the blood of the bullock, and sprinkle it upon the mercy seat, and before the mercy seat:
One goat is set free as the ‘scape goat’ from Lev 16:21, but one is also killed as a sin offering. Hence the belief by Christians that Jesus was the final sin offering and his sacrifice did away with this nonsense [although we end up with the nonsense of human/god sacrifice!].
The Jews believed that their sins were washed away by the two goats, Christians believe their sins are washed away by the blood of Jesus, but they fail to see that God wants genuine repentance and for us to walk in His way:-
18:1 The word of the LORD came unto me again, saying,
18:2 What mean ye, that ye use this proverb concerning the land of Israel, saying, The fathers have eaten sour grapes, and the children's teeth are set on edge?
18:3 As I live, saith the Lord GOD, ye shall not have occasion any more to use this proverb in Israel.
18:4 Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sinneth, it shall die.
18:5 But if a man be just, and do that which is lawful and right,
18:6 And hath not eaten upon the mountains, neither hath lifted up his eyes to the idols of the house of Israel, neither hath defiled his neighbour's wife, neither hath come near to a menstruous woman,
18:7 And hath not oppressed any, but hath restored to the debtor his pledge, hath spoiled none by violence, hath given his bread to the hungry, and hath covered the naked with a garment;
18:8 He that hath not given forth upon usury, neither hath taken any increase, that hath withdrawn his hand from iniquity, hath executed true judgment between man and man,
18:9 HATH WALKED IN MY STATUTES, AND HATH KEPT MY JUDGMENTS, TO DEAL TRULY; HE IS JUST, HE SHALL SURELY LIVE, SAITH THE LORD GOD.
