Leviticus 11:36

Nevertheless a fountain or pit, wherein there is plenty of water, shall be clean: but that which toucheth their carcass shall be unclean.

Nevertheless a spring or a cistern in which water is a gathered shall be clean: but that which touches their carcass shall be unclean.

Nevertheless a fountain or a pit wherein is a gathering of water shall be clean: but that which toucheth their carcass shall be unclean.

`Only -- a fountain or pit, a collection of water, is clean, but that which is coming against their carcase is unclean;

Nevertheless, a spring or cistern containing water will remain clean, but one who touches a carcass in it will be unclean.
