Exodus 14:17

And the LORD hardened the heart of Pharaoh king of Egypt, and he pursued after the children of Israel: and the children of Israel went out with an high hand.

And I will harden Pharaoh’s heart, that he shall follow after them; and I will be honoured upon Pharaoh, and upon all his host; that the Egyptians may know that I am the LORD. And they did so.

Therefore thus saith the Lord GOD unto them; Behold, I, even I, will judge between the fat cattle and between the lean cattle.

See now that I, even I, am he, and there is no god with me: I kill, and I make alive; I wound, and I heal: neither is there any that can deliver out of my hand.

For thus saith the Lord GOD; Behold, I, even I, will both search my sheep, and seek them out.

I, even I, have spoken; yea, I have called him: I have brought him, and he shall make his way prosperous.

I, even I, am he that comforteth you: who art thou, that thou shouldest be afraid of a man that shall die, and of the son of man which shall be made as grass;

And say, Ye mountains of Israel, hear the word of the Lord GOD; Thus saith the Lord GOD to the mountains, and to the hills, to the rivers, and to the valleys; Behold, I, even I, will bring a sword upon you, and I will destroy your high places.

Therefore thus saith the Lord GOD; Behold, I, even I, am against thee, and will execute judgments in the midst of thee in the sight of the nations.

Then I will walk contrary unto you also in fury; and I, even I, will chastise you seven times for your sins.

And I, behold, I establish my covenant with you, and with your seed after you;

And I will harden Pharaoh’s heart, and multiply my signs and my wonders in the land of Egypt.

For I will be unto Ephraim as a lion, and as a young lion to the house of Judah: I, even I, will tear and go away; I will take away, and none shall rescue him.

And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall die.

Therefore, behold, I, even I, will utterly forget you, and I will forsake you, and the city that I gave you and your fathers, and cast you out of my presence:

And I say unto thee, Let my son go, that he may serve me: and if thou refuse to let him go, behold, I will slay thy son, even thy firstborn.
