Exodus 9:1-7

1Then the LORD said to Moses, Go in to Pharaoh, and tell him, Thus saith the LORD God of the Hebrews, Let my people go, that they may serve me. 2For if thou shalt refuse to let them go, and wilt hold them still, 3Behold, the hand of the LORD is upon thy cattle which are in the field, upon the horses, upon the donkeys, upon the camels, upon the oxen, and upon the sheep: there shall be a very grievous plague. 4And the LORD shall make a difference between the cattle of Israel and the cattle of Egypt: and there shall nothing die of all that belong to the children of Israel. 5And the LORD appointed a set time, saying, To morrow the LORD shall do this thing in the land. 6And the LORD did that thing on the next day, and all the cattle of Egypt died: but of the cattle of the children of Israel died not one. 7And Pharaoh sent, and, behold, there was not one of the cattle of the Israelites dead. And the heart of Pharaoh was hardened, and he did not let the people go.
