Exodus 9:1-4

1And Jehovah said to Moses, Go in unto Pharaoh, and tell him, Thus saith Jehovah the 1God of the Hebrews: Let my people go, that they may serve me.

2For if thou refuse to let them go, and shalt retain them still,

3behold, the hand of Jehovah shall be on thy cattle which is in the field, on the horses, on the asses, on the camels, on the oxen and on the sheep, with a very grievous plague.

4And Jehovah will distinguish between the cattle of Israel and the cattle of Egypt; and there shall nothing die of all that the children of Israel have.
