Additionally, make poles of acacia wood for the altar and overlay them with bronze.
As God intended in the tabernacle to manifest his presence among his people, so there they were to pay their devotions to him, not in the tabernacle itself (into that only the priests entered as God's domestic servants), but in the court before the tabernacle, where, as common subjects, they attended.
Commenting on Exodus 27:1-8
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.
staves . . . rings--Those rings were placed at the side through which the poles were inserted on occasions of removal.
