Exodus 9:34-35

Wycliffe Bible

³⁴ Soothly Pharaoh saw that the rain had ceased, and the hail, and thunders, and he increased (his) sin; and the heart of him, and of his servants, was made grievous, (And when Pharaoh saw that the rain, and the hail, and the thunder, had ceased, he increased his sin; and his heart, and the hearts of his servants, were hardened,)

³⁵ and his heart was made hard greatly; neither he let go the sons of Israel, as the Lord commanded by the hand of Moses. (yea, his heart was greatly hardened; and he still would not let the Israelites go, as the Lord had said through Moses.)
