In Leviticus we are told that the blood that gives us salvation was poured out by God on the altar and that there was no atonement (as was salvation before) without the blood. Lev. 28:11.
We know that blood is only the blood of Christ, and it was used symbolically for atonement for 4,000 years. Some people say the salvation system was based on giving literal blood of animals, but scripture tells us God hated the blood of animals and that animal blood never, ever, gave atonement. The sacrificial system required giving up sin for atonement as the blood o Christ requires.
Atonement gave preserving souls in what was pictured as sleep rather than the life that Christ gives. When Christ died on the cross and the curtain was split these souls were able to walk the streets of Jerusalem as we are told in Matthews 27:52-53.

Gen 17:9-14 And God said to Abraham: "As for you, you shall keep My covenant, you and your descendants after you throughout their generations.
This

He who is eight days old among you shall be circumcised, every male child in your generations, he who is born in your house or bought with money from any foreigner who is not your descendant.
He who is born in your house and he who is bought with your money must be circumcised, and My covenant shall be in your flesh for an everlasting covenant.
And the uncircumcised male child, who is not circumcised in the flesh of his foreskin, that person shall be cut off from his people; he has broken My covenant."
This is the first bloodshed covenant with Abraham circumcised the flesh
1 Chron 21:26-28 And David built there an altar to the Lord, and offered burnt offerings and peace offerings, and called on the Lord; and He answered him from heaven by fire on the altar of burnt offering.
So the Lord commanded the angel, and he returned his sword to its sheath.
