Exodus 24 What you think of this?? Then Moses took half of the blood, and put it into bowls; and the rest he poured upon the altar.?

The whole chapter is awesome, especially when it culminates in Moses, Aaron, Nadab and Abihu plus 70 elders of Israel seeing the throne of God; under God's feet was a pavement like sapphire, clear as the sky.

Prior to that, Moses and the people of Israel had agreed to enter into a special covenant relationship with God, their Redeemer (Job 19:25-27) and that covenant was ratified with the animal sacrifices you mention.

When Jesus came as Redeemer, it was to fulfil that covenant and to usher in the New Covenant which the old one pointed towards. He redeemed by his own sacrificial blood, when He went silently, like a sheep to the slaughter, to be crucified. His was the only perfect sacrifice for sin there has ever been, for "the blood of bulls and goats cannot take away sin" (Hebrews 9:7-22 & 10:11-14).

So, yes, the New Testament [Covenant] book of Hebrews explains how what Moses did prefigured what the Son of God would do a few thousand years later, and that is why Christians partake of the broken bread and wine that speak to us of the broken body and shed blood of Christ.

However, I don't know what you mean by "covenant for the righteous". The Israelites in the Mosaic covenant were unrighteous, and all in Jesus' new covenant are unrighteous, in that they have no righteousness in and of themselves - see Romans 3:9-31 & Isaiah 64:7. Only God is righteous, and only by His righteousness being shown to the world at Golgotha can those receiving that provision be declared righteous, spiritually speaking.

Jesus has nothing to do with Exodus 24.

The covenant, the blood and the people. Compare to Matthew 26, Mark 14, Luke 22 1 Corinthians 11 to get a grasp on the "type/anti-type" application of OT yielding to the NT.

Jesus and his life were prefigured in the Old Testament many times.

But his sacrifice is more in keeping with the "Passover Lamb".

Just a description of sacrifice to dull the minds of the masses through horror.

That is like when Cedric predicted that Harry Potter would win the magical tournament, only in a more bloody setting.

Blood of wut??

This was symbolic of the sacrifice Jesus made for humanity in the past but for them at that time it was a future thing.

It's a cool story, but still ultimately just fiction.

Jesus never existed.
