Ezekiel 40:38-39

38There was a small building joined to the entrance room of the north gate. There was a door between this building and the entrance room. In that building, the priests washed the dead bodies of animals for burnt offerings.

39In the entrance room there were four tables, two on each side of the room. They killed the animals for sacrifices on these tables. They were animals for burnt offerings and also for sin offerings and for guilt offerings.
