⁷ And Pharaoh sent, and, behold, there was not one of the cattle of the Israelites dead. And the heart of Pharaoh was hardened, and he did not let the people go.

¹⁴ And the Lord said unto Moses, Pharaoh's heart is hardened, he refuseth to let the people go.

³² And Pharaoh hardened his heart at this time also, neither would he let the people go.

¹⁸ Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.

²⁰ But when his heart was lifted up, and his mind hardened in pride, he was deposed from his kingly throne, and they took his glory from him:

⁴ Because I knew that thou art obstinate, and thy neck is an iron sinew, and thy brow brass;

29 He, that being often reproved hardeneth his neck, shall suddenly be destroyed, and that without remedy.

⁴ He is wise in heart, and mighty in strength: who hath hardened himself against him, and hath prospered?

¹² And the Lord hardened the heart of Pharaoh, and he hearkened not unto them; as the Lord had spoken unto Moses.
