The holy chambers, located on both the north side and the south side, are buildings that connect the inner court with the outer court. The chambers on the pavement in the outer court are for the people to eat the offerings (Ezek. 40:17 and note Ezek. 40:171), whereas the holy chambers are for the priests to eat the offerings and also to place and store the offerings and to lay their priestly garments (vv. 13-14). Whereas the offerings signify Christ as our enjoyment, the priestly garments signify Christ as our expression (see notes on Exo. 28:2).
In the holy chambers we reach the highest peak of spiritual experience. To live in the holy chambers is to live in Christ, to eat the offerings in the holy chambers is to eat Christ, and to wear the holy garments is to wear Christ for His expression.
