Ezekiel 40:38

There was a chamber with its door in the vestibule of the gate, where the burnt offering was to be washed.

A room with a doorway was by the portico in each of the inner gateways, where the burnt offerings were washed.

There was a chamber whose door opened into the gate’s portico. The burnt offering was to be washed there.

A door led from the entry room of one of the inner gateways into a side room, where the meat for sacrifices was washed.

And a chamber with its doorway was in the pilasters at the gates, and there they rinsed off the burnt offering.

And the chambers and the entries thereof were by the posts of the gates, where they washed the burnt offering.
