Keluaran 29:7-9

29:7 You are to take the anointing oil and pour it on his head and anoint him. ¹  29:8 You are to present his sons and clothe them with tunics 29:9 and wrap the sashes around Aaron and his sons ²  and put headbands on them, and so the ministry of priesthood will belong to them by a perpetual ordinance. Thus you are to consecrate ³  Aaron and his sons.

[29:7]  ¹ sn The act of anointing was meant to set him apart for this holy service within the house of Yahweh. The psalms indicate that no oil was spared in this ritual, for it ran down his beard and to the hem of his garment. Oil of anointing was used for all major offices (giving the label with the passive adjective “mashiah” (or “messiah”) to anyone anointed. In the further revelation of Scripture, the oil came to signify the enablement as well as the setting apart, and often the Holy Spirit came on the person at the anointing with oil. The olive oil was a symbol of the Spirit in the OT as well (Zech 4:4-6). And in the NT “anointing” signifies empowerment by the Holy Spirit for service.

[29:9]  ² tc Hebrew has both the objective pronoun “them” and the names “Aaron and his sons.” Neither the LXX nor Leviticus 8:13 has “Aaron and his sons,” suggesting that this may have been a later gloss in the text.

[29:9]  ³ tn Heb “and you will fill the hand” and so “consecrate” or “ordain.” The verb draws together the individual acts of the process.
