5 and every firstborn son in Egypt will die, from the king's son, who is heir to the throne, to the son of the slave woman who grinds corn. The firstborn of all the cattle will die also.
6 There will be loud crying all over Egypt, such as there has never been before or ever will be again.
7 But not even a dog will bark at the Israelites or their animals. Then you will know that I, the Lord, make a distinction between the Egyptians and the Israelites.’ ”
8 Moses concluded by saying, “All your officials will come to me and bow down before me, and they will beg me to take all my people and go away. After that, I will leave.” Then in great anger Moses left the king.
9 The Lord had said to Moses, “The king will continue to refuse to listen to you, in order that I may do more of my miracles in Egypt.”
10 Moses and Aaron performed all these miracles before the king, but the Lord made him stubborn, and he would not let the Israelites leave his country.
