'Ledge' in the Bible

And you shall put it under the ledge of the altar, so that the grid will extend halfway up the altar.

He made for the altar a grating of bronze mesh under its rim, extending halfway up it.

From the base on the ground to the lower ledge shall be two cubits and the width one cubit; and from the smaller ledge to the larger ledge shall be four cubits and the width one cubit.

The ledge shall be fourteen cubits long by fourteen wide on its four sides, and the border around it shall be half a cubit; and its base shall be a cubit all around, and its steps shall face the east.”

And you shall take some 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 border all around; thus you shall cleanse it (from sin) and make atonement for it.

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