(6) Staves for the altar.--See Note 2 on Exodus 27:4.

Verses 6, 7. - Staves, or polos, were needed for the carriage of the altar from place to place, as for the ark (Exodus 25:13) and the table of shew-bread (ib, ver. 28). They were to be inserted into the rings mentioned in ver. 4. As the altar was of bronze, so the rings were to be of bronze, and the staves overlaid with bronze. There is a gradual descent in the preciousness of the materials from the holy of holies to the holy place, and from that to the court.

27:1-8 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.And thou shalt make staves for the altar, staves of shittim wood,.... Like those that were made for the ark, and for the same purpose:

and overlay them with brass; with plates of brass, whereas those for the ark were overlaid with gold.
