Ezekiel 46:21-23

Young's Literal Translation

²¹ And he bringeth me out unto the outer court, and causeth me to pass over unto the four corners of the court, and lo, a court in a corner of the court, a court in a corner of the corner.

²² In the four corners of the court [are] perfume courts, forty long, and thirty broad, one measure [is] to the four corners.

²³ And a row [is] round about in them, round about to them four, and made with boilers under the rows round about.
