16. And the altar shall be twelve cubits long, twelve wide, square in the four corners.
17. And the ledge shall be fourteen cubits long and fourteen wide on its four sides; and the rim around it shall be half a cubit wide; and its base shall be a cubit all around; and its steps shall face toward the east.

20. And you shall take some of its blood, and put it on the four horns of it, and on the four corners of the ledge, and upon the rim around it: thus shall you cleanse and purge it.
