The altar of burnt offerings. (1-8) The court of the tabernacle. (9-19) The oil for the lamps. (20,21)
Verses 1-8 In the court before the tabernacle, where the people attended, was an altar, to which they must bring their sacrifices, and on which their priests must offer them to God. It was of wood overlaid with brass. A grate of brass was let into the hollow of the altar, about the middle of which the fire was kept, and the sacrifice burnt. It was made of net-work like a sieve, and hung hollow, that the ashes might fall through. This brazen altar was a type of Christ dying to make atonement for our sins. The wood had been consumed by the fire from heaven, if it had not been secured by the brass: nor could the human nature of Christ have borne the wrath of God, if it had not been supported by Divine power.
Verses 9-19 The tabernacle was enclosed in a court, about sixty yards long and thirty broad, formed by curtains hung upon brazen pillars, fixed in brazen sockets. Within this enclosure the priests and Levites offered the sacrifices, and thither the Jewish people were admitted. These distinctions represented the difference between the visible nominal church, and the true spiritual church, which alone has access to God, and communion with him.
Verses 20-21 The pure oil signified the gifts and graces of the Spirit, which all believers receive from Christ, the good Olive, and without which our light cannot shine before men. The priests were to light the lamps, and tend them. It is the work of ministers, by preaching and expounding the Scriptures, which are as a lamp, to enlighten the church, God's tabernacle upon earth. Blessed be God, this light is not now confined to the Jewish tabernacle, but is a light to lighten the gentiles, and for salvation unto the ends of the earth.
This chapter treats of the altar of burnt offering, and of all things relative to it, Ex 27:1-8, of the court of the tabernacle, its hangings on each side, with pillars, sockets, and hooks for them, Ex 27:9-19 and it is concluded with an order to the Israelites to bring oil olive for the lamp of the sanctuary, Ex 27:20,21.
