'Ledge' in the Bible

And thou shalt put it under the ledge round the altar beneath, that the net may reach halfway up the altar.

And he made for the altar a grating of network of brass, under the ledge round it beneath, reaching halfway up.

And from the bottom upon the ground to the lower ledge 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 a cubit.

And the ledge shall be fourteen cubits long by fourteen broad in the four sides thereof; and the border about it shall be half a cubit; and the bottom thereof shall be a cubit round about; and the steps thereof shall look toward the east.

And thou shalt take of the blood thereof, and put it on the four horns of it, and on the four corners of the ledge, and upon the border round about: thus shalt thou cleanse it and make atonement for it.

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