Êxodo 9:7

7 Faraó mandou ver, e eis que do rebanho de Israel não morrera nem um sequer; porém o coração de Faraó se endureceu, e não deixou ir o povo.

7 And Pharaoh sent, and, behold, there was not so much as one of the cattle of the Israelites dead. But the heart of Pharaoh was stubborn, and he did not let the people go.
