Chosen from among men
Aaron and the Levitical priesthood
Exodus 25–27 records the building of the tabernacle, where God dwelt among the Israelites. In chapter 28 God appoints Aaron, of the tribe of Levi, and his sons as priests. Leviticus 8 is their ordination: the ceremony that set them apart, consecrated them and authorised them to serve. From then on Aaron and his descendants served as priests and high priests for Israel, the Levitical priesthood.
Gifts and sacrifices
Gifts were offered as thanksgiving; sacrifices were offered in repentance, to seek forgiveness. The NLT puts it plainly: “He presents their gifts to God and offers sacrifices for their sins.”
What the high priest offered: the burnt offering, gift and sacrifice (Lev 1; 3:8–13); the grain offering, a gift (Lev 2; 6:14–18); the peace offering, a gift (Lev 3; 7:11–34); the sin offering, a sacrifice (Lev 4:1–5:13); the guilt offering, a sacrifice (Lev 5:14–6:7); his personal daily grain offering (Lev 6:19–23); the daily incense offering (Exod 30:7–8); and once a year, the Day of Atonement (Lev 16).
The ignorant and the wayward
The ignorant are those who stumble or wander off course through spiritual weakness, blindness or lack of understanding. They do not rebel against God on purpose; they keep making mistakes because they lack discernment. The wayward are those who deliberately turn aside: they know better, or resist guidance, and leave the right path out of defiance or stubbornness.
A high priest chosen from among men could deal gently with both, because he himself was beset with weakness. That same weakness meant he had to offer sacrifice for his own sins before he offered for the people.
Called by God
Honor here is the worth ascribed to a person. No one could take it for himself. The high priest was appointed by God, not by his own ambition or desire, just as Aaron was.
“Then bring near to you Aaron your brother, and his sons with him, from among the people of Israel, to serve me as priests—Aaron and Aaron’s sons, Nadab and Abihu, Eleazar and Ithamar.”
Aaron called by God, “just as Aaron was.”
“Aaron shall offer the bull as a sin offering for himself and shall make atonement for himself and for his house.”
On the Day of Atonement the high priest offered first for himself.
“Then bring near to you Aaron your brother, and his sons with him, from among the people of Israel, to serve me as priests—Aaron and Aaron’s sons, Nadab and Abihu, Eleazar and Ithamar.”
