Hebrews 9:11-12
Christ’s Service in the Heavenly Sanctuary
9:11 But now Christ has come as the high priest of the good things to come. He passed through the greater and more perfect tent not made with hands, that is, not of this creation,
9:12 and he entered once for all into the most holy place not by the blood of goats and calves but by his own blood, and so he himself secured eternal redemption.
Hebrews 9:15-17
9:15 And so he is the mediator of a new covenant, so that those who are called may receive the eternal inheritance he has promised, since he died to set them free from the violations committed under the first covenant.
9:16 For where there is a will, the death of the one who made it must be proven.
9:17 For a will takes effect only at death, since it carries no force while the one who made it is alive.
