Exodus 9:33-35

Darby Translation

³³ And Moses went out of the city from Pharaoh, and spread out his hands to Jehovah; and the thunders and hail ceased, and the rain was not [any more] poured on the earth.

³⁴ And Pharaoh saw that the rain and the hail and the thunders had ceased, and he sinned yet more, and hardened his heart, he, and his bondmen.

³⁵ And the heart of Pharaoh was stubborn, neither would he let the children of Israel go, as Jehovah had spoken by Moses.
