But there won't be any need for the Israelites to cry. Things will be so quiet that not even a dog will be heard barking. Then you Egyptians will know that the LORD is good to the Israelites, even while he punishes you.
When you see this happen, you will celebrate; your strength will return faster than grass can sprout. Then everyone will know that the LORD is present with his servants, but he is angry with his enemies.
We know that everything in the Law was written for those who are under its power. The Law says these things to stop anyone from making excuses and to let God show that the whole world is guilty.
