Exodus 9:2-4

Amplified Bible, Classic Edition

² If you refuse to let them go and still hold them,

³ Behold, the hand of the Lord [will fall] upon your livestock which are out in the field, upon the horses, the donkeys, the camels, the herds and the flocks; there shall be a very severe plague.

⁴ But the Lord shall make a distinction between the livestock of Israel and the livestock of Egypt, and nothing shall die of all that belongs to the Israelites.
