'High Priest' in the Bible

but into the second [inner tabernacle, the Holy of Holies], only the high priest enters [and then only] once a year, and never without [bringing a sacrifice of] blood, which he offers [as a substitutionary atonement] for himself and for the sins of the people committed in ignorance.

But when Christ appeared as a High Priest of the good things to come [that is, true spiritual worship], He entered through the greater and more perfect tabernacle, not made with hands, that is to say, not a part of this [material] creation.

nor did He [enter into the heavenly sanctuary to] offer Himself again and again, as the high priest enters the Holy Place every year with blood that is not his own.

For the bodies of those animals whose blood is brought into the sanctuary by the high priest as an offering for sin, are burned outside the camp.
