'Flat' in the Bible

And take a flat iron plate, and put it for a wall of iron between you and the town: and let your face be turned to it, and it will be shut in and you will make an attack on it. This will be a sign to the children of Israel.

So I went in and saw; and there every sort of living thing which goes flat on the earth, and unclean beasts, and all the images of the children of Israel, were pictured round about on the wall.
