20 When they go into the tent of meeting, they shall wash with water, that they may not die; or when they come near to the altar to serve, to burn an offering by fire to Jehovah. 21 And they shall wash their hands and their feet, that they may not die; and it shall be an everlasting statute for them, for him and for his seed throughout their generations.

The Anointing Oil and the Incense

22 And Jehovah spoke to Moses, saying, 23 And thou, take best spices—of liquid myrrh five hundred [shekels], and of sweet cinnamon the half—two hundred and fifty, and of sweet myrtle two hundred and fifty, 24 and of cassia five hundred, after the shekel of the sanctuary, and of olive oil a hin; 25 and make of it an oil of holy ointment, a perfume of perfumery after the work of the perfumer: it shall be the holy anointing oil. 26 And thou shalt anoint the tent of meeting with it, and the ark of the testimony, 27 and the table and all its utensils, and the lamp-stand and its utensils, and the altar of incense, 28 and the altar of burnt-offering and all its utensils, and the laver and its stand. 29 And thou shalt hallow them, that they may be most holy: whatever toucheth them shall be holy. 30 And Aaron and his sons thou shalt anoint, and shalt hallow them, that they may serve me as priests. 31 And thou shalt speak to the children of Israel, saying, A holy anointing oil shall this be unto me throughout your generations. 32 Upon man's flesh shall it not be poured, neither shall ye make [any] like it, after the preparation of it: it is holy—holy shall it be unto you. 33 Whoever compoundeth [any] like it, or whoever putteth [any] of it upon any strange thing, shall be cut off from his peoples.

Matthew Henry's Commentary on Exodus 30:20-33

Commentary on Exodus 30:17-21

(Read Exodus 30:17-21)

A large vessel of brass, holding water, was to be set near the door of the tabernacle. Aaron and his sons must wash their hands and feet at this laver, every time they went in to minister. This was to teach them purity in all their services, and to dread the pollution of sin. They must not only wash and be made clean, when first made priests, but must wash and be kept clean, whenever they went to minister. It teaches us daily to attend upon God, daily to renew our repentance for sin, and our looking to the blood of Christ for remission; for in many things we daily offend.

Commentary on Exodus 30:22-38

(Read Exodus 30:22-38)

Directions are here given for making the holy anointing oil, and the incense to be used in the service of the tabernacle. To show the excellency of holiness, there was this spiced oil in the tabernacle, which was grateful to the sight and to the smell. Christ's name is as ointment poured forth, Ecclesiastes 7:1. The incense burned upon the golden altar was prepared of sweet spices. When it was used, it was to be beaten very small; thus it pleased the Lord to bruise the Redeemer, when he offered himself for a sacrifice of a sweet-smelling savour. The like should not be made for any common use. Thus God would keep in the people's minds reverence for his own services, and teach us not to profane or abuse any thing whereby God makes himself known. It is a great affront to God to jest with sacred things, and to make sport with his word and ordinances. It is most dangerous and fatal to use professions of the gospel of Christ to forward wordly interests.
