Exodus 11:7-9

7But no trouble will happen to the Israelite people. Not even a dog will frighten them or their animals. Then you will know that I, the Lord, make a difference between Egypt and Israel.” ’

8Moses continued to say to the king, ‘All your officers will come to me. They will fall down in front of me and they will say, “Now go! Leave here with all your people.” After that, I will leave.’ After he said that, Moses left Pharaoh. Moses was very angry.

9The Lord had already said to Moses, ‘Pharaoh will refuse to listen to you. But that will give me the chance to do even greater miracles in Egypt.’
