Êxodo 7:18

18 Os peixes que estão no rio morrerão, o rio cheirará mal, e os egípcios terão nojo de beber água do rio.

18 And the fish in the Nile will come to destruction, and the river will send up a bad smell, and the Egyptians will not be able, for disgust, to make use of the water of the Nile for drinking.
