Ezekiel 40:38

Its chambers and its door-ways, and its porches at the second gate [served as] a drain,

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

A room with its door was by the posts at the gates. They washed the burnt offering there.

And euery chamber, and the entrie thereof was vnder the postes of the gates: there they washed the burnt offring.
