And from the hollow of the ground unto the lower ledge, shall be two cubits, and the breadth, one cubit,- and from the smaller ledge unto the larger ledge, shall be four cubits, and the breadth, a cubit.

And the ledge shall he fourteen in length, by fourteen in breadth, unto the four sides thereof, - and the boundary round about it shall be half a cubit and the hollow thereof a cubit round about, with the steps thereof looking toward the east. I

Then shalt thou take of the blood thereof and place upon the four horns thereof and on the four corners of the ledge, and on the boundary, round about, - and shalt cleanse it from sin and put a propitiatory-covering over it.

then shall the priest take of the blood of the sin-bearer and put upon the door-posts of the house, and upon the four corners of the ledge of the altar and upon the door-posts of the gate of the inner court.
