'Flat' in the Bible

And God said, Let us make man in our image, like us: and let him have rule over the fish of the sea and over the birds of the air and over the cattle and over all the earth and over every living thing which goes flat on the earth.

And the Lord God said to the snake, Because you have done this you are cursed more than all cattle and every beast of the field; you will go flat on the earth, and dust will be your food all the days of your life:

And it came about that in their wandering from the east, they came to a stretch of flat country in the land of Shinar, and there they made their living-place.
