'Ledge' in the Bible

You shall put it under the ledge around the altar beneath, that the net may reach halfway up the altar.

He made for the altar a grating of a network of brass, under the ledge around it beneath, reaching halfway up.

From the bottom on 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.

The ledge shall be fourteen [cubits] long by fourteen broad in the four sides of it; and the border about it shall be half a cubit; and its bottom shall be a cubit around; and its steps shall look toward the east.

You shall take of its blood, and put it on the four horns of it, and on the four corners of the ledge, and on the border all around: thus you shall cleanse it and make atonement for it.

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