Exodus 11:5

5 Every oldest son in Egypt will die. The oldest son of Pharaoh, who sits on the throne, will die. The oldest son of the female slave, who works at her hand mill, will die. All of the male animals that were born first to their mothers among the cattle will also die.

Exodus 11:5 In-Context

3 The LORD caused the Egyptians to treat the Israelites in a kind way. Pharaoh's officials and the people had great respect for Moses.
4 Moses said, "The LORD says, 'About midnight I will go through every part of Egypt.
5 Every oldest son in Egypt will die. The oldest son of Pharaoh, who sits on the throne, will die. The oldest son of the female slave, who works at her hand mill, will die. All of the male animals that were born first to their mothers among the cattle will also die.
6 There will be loud crying all over Egypt. It will be worse than it's ever been before. And nothing like it will ever be heard again.
7 " 'But among the people of Israel not even one dog will bark at any man or animal.' Then you will know that the LORD treats Egypt differently from us.
