Ezekiel 46:21-24
46:21 Then he brought me out to the outer court and led me past the four corners of the court, and I noticed that in every corner of the court there was a court.
46:22 In the four corners of the court were small courts, 70 feet in length and 52½ feet in width; the four were all the same size.
46:23 There was a row of masonry around each of the four courts, and places for boiling offerings were made under the rows all around.
46:24 Then he said to me, “These are the houses for boiling, where the ministers of the temple boil the sacrifices of the people.”
