- A waterfall is any point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf.
Then the priest shall come and look, and, behold, if the plague be spread in the house, it is a fretting leprosy in the house; it is unclean.
Leviticus 14:44 KJV
