Exodus 9:7

Pharaoh sent It seems as if Pharaoh, notwithstanding all he had seen, could not conceive that such a distinction could be made between cattle feeding together in the same or similar pastures, that those of the Egyptians alone should be stricken, while those of the Israelites were not affected; and therefore he sent expressly to know the truth of it: when behold, (and well might it be said, behold! for it was worthy of both notice and admiration,) there was not one of the cattle of the Israelites dead But, notwithstanding this most convincing evidence of the distinguishing favour of God toward his people, such was the unwillingness of Pharaoh to part with the advantage which the service of the Israelites was to him, that he could not bring himself to consent to their departure.
