Ezekiel 46:20-21

20He said to me, “This is the place where the priests must boil the meat for the guilt offering and the offering for sin. This is the place where they must bake grain offerings so that they don’t have to bring the offerings into the outer courtyard. This way they won’t transfer holiness to the people.”

21Then the man led me to the outer courtyard and took me past the four corners of the courtyard. I saw that in each corner of the courtyard there was a smaller courtyard.
