Exodus 11:7-9

Amplified Bible

⁷ But not even a dog will ^[a]threaten any of the Israelites, whether man or animal, so that you may know [without any doubt] and acknowledge how the Lord makes a distinction between Egypt and Israel.’ ⁸ All these servants of yours will come down to me and bow down before me, saying, ‘Get out, you and all the people who follow you.’ After that I will leave.” And he left Pharaoh in the heat of anger.

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