Exodus 11:7-9

7But among the Israelites it will be so peaceful that not even a dog will bark. Then you will know that the Lord makes a distinction between the Egyptians and the Israelites.

8All the officials of Egypt will run to me and fall to the ground before me. ‘Please leave!’ they will beg. ‘Hurry! And take all your followers with you.’ Only then will I go!” Then, burning with anger, Moses left Pharaoh.

9Now the Lord had told Moses earlier, “Pharaoh will not listen to you, but then I will do even more mighty miracles in the land of Egypt.”
