'Edges' in the Bible

For this cause the Lord is sending on them the waters of the River, deep and strong, even the king of Assyria and all his glory: and it will come up through all its streams, overflowing all its edges:

“Behold, I have made you a new, sharp threshing sledge with double edges;You will thresh the mountains and pulverize them,And will make the hills like chaff.
