'High Priest' in the Bible

Then that high priest must take some of the blood of the bull and bring it to the Meeting Tent.

Then the high priest must bring some of the blood of the bull to the Meeting Tent,

The high priest who succeeds him from among his sons must do it. It is a perpetual statute; it must be offered up in smoke as a whole offering to the Lord.

Moses then put the breastpiece on Aaron, and he put in the breastpiece the Urim and the Thummim [the sacred articles the high priest used when seeking God’s will concerning the nation].

There shall be no person in the Tent of Meeting when the high priest goes in to make atonement in the Holy Place [within the veil] until he comes out, so that he may make atonement for himself (his own sins) and for his household and for all the congregation of Israel.

"The priest who is anointed and ordained to act as high priest in place of his father is to make atonement. He is to put on the linen garments, the holy garments,

Then the Lord said to Moses, “Speak to the priests, the sons of Aaron, and say to them:‘No one shall defile himself [that is, become ceremonially unclean] for the dead among his people [by touching a corpse or assisting in preparing it for burial],

And he that is the high priest among his brethren, upon whose head the anointing oil was poured, and that is consecrated to put on the garments, shall not uncover his head, nor rend his clothes;

so that he will not profane or dishonor his children among his people; for I am the Lord who sanctifies the high priest.’”

The bread of the Presence shall be for Aaron and his sons, and they shall eat it in a sacred place, for it is for Aaron a most holy portion of the offerings by fire to the Lord, his portion forever.”
