And the chambers and the entries thereof were by the posts of the gates, where they washed the burnt offering.
The chambers, and the entries - literally, a chamber and its door.
By the posts - i:e., at or close by the posts or columns.
Where they washed the burnt offering. This does not apply to all the gates, but only to the north gate; for Leviticus 1:11 directs the sacrifices to be killed north of the altar; and Ezekiel 8:5 calls the north gate "the gate of the altar." And Ezekiel 40:40 particularly mentions the north gate.
