Exodus 9:5-7

Young's Literal Translation

⁵ and Jehovah setteth an appointed time, saying, To-morrow doth Jehovah do this thing in the land.'

⁶ And Jehovah doth this thing on the morrow, and all the cattle of Egypt die, and of the cattle of the sons of Israel not one hath died;

⁷ and Pharaoh sendeth, and lo, not even one of the cattle of Israel hath died, and the heart of Pharaoh is hard, and he hath not sent the people away.
