Hebrews 9:14

10 They consist only in food and drink and special washings—external regulations imposed until the time of reform.

11 But when Christ came as high priest of the good things that have come, He went through the greater and more perfect tabernacle that is not made by hands and is not a part of this creation.

12 He did not enter by the blood of goats and calves, but He entered the Most Holy Place once for all by His own blood, thus securing eternal redemption.

13 For if the blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that their bodies are clean,

14 how much more will the blood of Christ, who through the eternal Spirit offered Himself unblemished to God, purify our consciences from works of death, so that we may serve the living God!

15 Therefore Christ is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, now that He has died to redeem them from the transgressions committed under the first covenant.

16 In the case of a will, it is necessary to establish the death of the one who made it,

17 because a will does not take effect until the one who made it has died; it cannot be executed while he is still alive.

18 That is why even the first covenant was not put into effect without blood.
