From the bottom or gutter on the ground to the lower ledge or brim shall be two cubits, and the breadth one cubit; and from the lesser ledge to the greater ledge shall be four cubits, and the breadth one cubit.

And the ledge shall be fourteen cubits long and fourteen cubits broad on its four sides, and the border about it shall be half a cubit; and its bottom or gutter shall be a cubit deep and wide, and its ascent [not steps] shall face the east.

And you shall take of its blood and put it on the four horns of [the altar of burnt offering] and on the four corners of the ledge and on the rim or border round about. Thus shall you cleanse and make atonement for [the altar].

And the priest shall take some of the blood of the sin offering and put it upon the doorposts of the temple and upon the four corners of the ledge of the altar and upon the posts of the gate of the inner court.
