Hebrews 6:6

6:6 and then have committed apostasy, to renew them again to repentance, since they are crucifying the Son of God for themselves all over again and holding him up to contempt.

Hebrews 9:25-26

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.
