Isaiah 6:10

For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.

Hear now this, O foolish people, and without understanding; which have eyes, and see not; which have ears, and hear not: understanding: Heb. heart

But Jeshurun waxed fat, and kicked: thou art waxen fat, thou art grown thick, thou art covered with fatness; then he forsook God which made him, and lightly esteemed the Rock of his salvation.

For the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them.

They are inclosed in their own fat: with their mouth they speak proudly.

But they refused to hearken, and pulled away the shoulder, and stopped their ears, that they should not hear. pulled...: Heb. they gave a backsliding shoulder stopped: Heb. made heavy

To whom shall I speak, and give warning, that they may hear? behold, their ear is uncircumcised, and they cannot hearken: behold, the word of the LORD is unto them a reproach; they have no delight in it.

Their heart is as fat as grease; but I delight in thy law.

O LORD, why hast thou made us to err from thy ways, and hardened our heart from thy fear? Return for thy servants' sake, the tribes of thine inheritance.

And I, behold, I will harden the hearts of the Egyptians, and they shall follow them: and I will get me honour upon Pharaoh, and upon all his host, upon his chariots, and upon his horsemen.

To the one we are the savour of death unto death; and to the other the savour of life unto life. And who is sufficient for these things?

But the LORD hardened Pharaoh's heart, and he would not let them go.
