Exodus 9:5-7

New American Standard Bible

⁵ And the Lord set a definite time, saying, “Tomorrow the Lord will do this thing in the land.” ⁶ So the Lord did this thing on the next day, and ^(A)all the livestock of Egypt died; ^(B)but not one of the livestock of the sons of Israel died. ⁷ And Pharaoh sent men, and they learned that, behold, not even one of the livestock of Israel was dead. But ^(C)the heart of Pharaoh was ^[a]hardened, and he did not let the people go.
