Exodus 11:7-9

71But not even a dog will 2threaten any of the sons of Israel, nor anything from person to animal, so that you may 3learn how the Lord distinguishes between Egypt and Israel.’ 8And 4all these servants of yours will come down to me and bow themselves 5before me, saying, ‘Go out, you and all the people who 6follow you,’ and after that I will go out.” 7And he left Pharaoh in the heat of anger.

9Then the Lord said to Moses, “8Pharaoh will not listen to you, so 9that My wonders will be multiplied in the land of Egypt.”
