Hebrews 9:12
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 9:24-26
9:24 For Christ did not enter a sanctuary made with hands – the representation of the true sanctuary – but into heaven itself, and he appears now in God’s presence for us.
9:25 And he did not enter to offer himself again and again, the way the high priest enters the sanctuary year after year with blood that is not his own,
9:26 for then he would have had to suffer again and again since the foundation of the world. But now he has appeared once for all at the consummation of the ages to put away sin by his sacrifice.
