Without blood there is no atonement for sins.

Let us first see the Day of Atonement in context: It is true that the first goat was used as a sin offering. But consider the second goat. The sins of the people are laid on the second goat and that specific goat shall bear the iniquity of the people. As the book of Hebrew says "But only the high priest entered the inner room, and that only once a year, and never without blood, which he offered for himself and for the sins the people had committed in ignorance." So the first goat, could be interpreted as being killed and sacrifice for purification of the Holy Place and for the unintentional sins of the people 20 "And when he has made an end of atoning for the Holy Place, the tabernacle of meeting, and the altar, he shall bring the live goat. 21 Aaron shall lay both his hands on the head of the live goat, confess over it all the iniquities of the children of Israel, and all their transgressions, concerning all their sins, putting them on the head of the goat, and shall send it away into the wilderness by the hand of a suitable man. 22 The goat shall bear on itself all their iniquities to an uninhabited land; and he shall release the goat in the wilderness. And as for the second goat, he carries the intentional sins of the people in the wilderness without shedding blood. Furthermore Daniel, who was considered righteous never offer any Yom Kippur offering and thus was consider righteous without blood and without the Day of atonement sacrifice. " My opponent goes as far to say the " it (referring to Lev 17:11) does not talk about atonement whatsoever"" I meant that the context talks about food and not atonement, not that atonement is not mentioned, sorry if I was not clear about that. Jesus was often referred to in metaphors to represent what was used in the Old Covenant, Metaphors should not be used, the law is not a shadow or type. G-d asked the Jewish people to do exactly as prescribed and not to turn to the right or to the left... "Be strong and very courageous. Be careful to obey all the law my servant Moses gave you; do not turn from it to the right or to the left, that you may be successful wherever you go." Joshua 1:7 Remember what happened to Aaron's son who did not follow what G-d told them. What would G-d ask us to trust in a sacrifice that was not mandate by Him in His words. "Behold, the Lamb of God, who takes away the sin of the world!" Again, interestedly enough, no Male sheep were ever offered as a sin offering. "Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us." Only animal blood is clean. Men's blood is not clean. Dead human corps are the worst unclean thing that could be as per the Law of G-d. "Whoever touches a human corpse will be unclean for seven days. Number 19:11 That's what G-d thinks about human sacrifices: Jeremiah 19:4-5: For they have forsaken me and made this a place of foreign gods; they have burned sacrifices in it to gods that neither they nor their fathers nor the kings of Judah ever knew, and they have filled this place with the blood of the innocent. They have built the high places of Baal to burn their sons in the fire as offerings to Baal - something I did not command or mention, nor did it enter my mind. New Covenant: this is another topic, but as per Jeremiah, this has not happened yet. I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. 34 And no longer shall each one teach his neighbour and each his brother, saying, "Know the Lord," for they shall all know me, from the least of them to the greatest, declares the Lord. Finally, as we saw in our previous round, Flour is used for atonement. If flour is used once, then blood is not always needed, thus the book of Hebrews is wrong.
