'Shelf' in the Bible

And put the network under the shelf round the altar so that the net comes half-way up the altar.

And from the base on the earth level to the lower shelf, the altar is two cubits high and a cubit wide; and from the smaller shelf to the greater shelf it is four cubits high and a cubit wide.

And the shelf is fourteen cubits long and fourteen cubits wide, on its four sides; the edge round it is half a cubit; the base of it is a cubit all round, and its steps are facing the east.

You are to take some of its blood and put it on the four horns and on the four angles of the shelf and on the edge all round: and you are to make it clean and free from sin.

And the priest is to take some of the blood of the sin-offering and put it on the uprights at the sides of the doors of the house, and on the four angles of the shelf of the altar, and on the sides of the doorway of the inner square.
