Exodus 9:5-7

Amplified Bible, Classic Edition

⁵ And the Lord set a time, saying, Tomorrow the Lord will do this thing in the land.

⁶ And the Lord did that the next day, and all [kinds of] the livestock of Egypt died; but of the livestock of the Israelites not one died.

⁷ Pharaoh sent to find out, and behold, there was not one of the cattle of the Israelites dead. But the heart of Pharaoh was hardened [his mind was set] and he did not let the people go.
