Exodus 9:1-3

King James Version

9 Then the Lord said unto Moses, Go in unto Pharaoh, and tell him, Thus saith the Lord God of the Hebrews, Let my people go, that they may serve me.

² For if thou refuse to let them go, and wilt hold them still,

³ Behold, the hand of the Lord is upon thy cattle which is in the field, upon the horses, upon the asses, upon the camels, upon the oxen, and upon the sheep: there shall be a very grievous murrain.
