Hebrews 9:14 contrasts Christ's blood that cleanses our conscience with animal blood, showing the superior sacrifice of the new covenant.

Hebrews 9:22 states the principle that without blood there is no forgiveness, explaining why the first covenant required blood inauguration.

Exodus 24:3-8 records the very event—Moses reading the covenant and sprinkling blood, the basis for Hebrews' argument about the first covenant's inauguration.

Exodus 24:6 depicts Moses dividing the blood—half on the altar—providing the specific ritual detail that Hebrews 9:18 alludes to.

Exodus 24:8 contains the words 'the blood of the covenant' that Hebrews later quotes, the climactic moment of the inauguration.
