King James Version
“And the heart of Pharaoh was hardened, neither would he let the children of Israel go; as the LORD had spoken by Moses.”
Context
32But the wheat and the rie were not smitten: for they not grown up.
33And Moses went out of the city from Pharaoh, and spread abroad his hands unto the LORD: and the thunders and hail ceased, and the rain was not poured upon the earth.
34And when Pharaoh saw that the rain and the hail and the thunders were ceased, he sinned yet more, and hardened his heart, he and his servants.
35And the heart of Pharaoh was hardened, neither would he let the children of Israel go; as the LORD had spoken by Moses.
