Exodus 11:4-7
Exodus 11:4-7 MSG
Then Moses confronted Pharaoh: “GOD’s Message: ‘At midnight I will go through Egypt and every firstborn child in Egypt will die, from the firstborn of Pharaoh, who sits on his throne, to the firstborn of the slave girl working at her hand mill. Also the firstborn of animals. Widespread wailing will erupt all over the country, lament such as has never been and never will be again. But against the Israelites—man, woman, or animal—there won’t be so much as a dog’s bark, so that you’ll know that GOD makes a clear distinction between Egypt and Israel.’
