The Lord said to Moses, "Go to the king and tell him that the Lord, the God of the Hebrews, says, "Let my people go, so that they may worship me.
If you again refuse to let them go,
I will punish you by sending a terrible disease on all your animals - your horses, donkeys, camels, cattle, sheep, and goats.
I will make a distinction between the animals of the Israelites and those of the Egyptians, and no animal that belongs to the Israelites will die.
I, the Lord, have set tomorrow as the time when I will do this.' "
The next day the Lord did as he had said, and all the animals of the Egyptians died, but not one of the animals of the Israelites died.
The king asked what had happened and was told that none of the animals of the Israelites had died. But he was stubborn and would not let the people go.
