But when Pharaoh saw that there was a respite, he hardened his heart, and hearkened not unto them; as the LORD had said.

Why then do you harden your hearts, as the Egyptians and Pharaoh hardened their hearts? when he had worked wonderfully among them, did they not let the people go, and they departed?

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:

But when some were hardened, and believed not, but spoke evil of that way before the multitude, he departed from them, and separated the disciples, arguing daily in the school of one Tyrannus.

But according to your hardness and unrepentant heart treasure up unto yourself wrath against the day of wrath and revelation of the righteous judgment of God;

But exhort one another daily, while it is called Today; lest any of you be hardened through the deceitfulness of sin.

See that you refuse not him that speaks. For if they escaped not who refused him that spoke on earth, much more shall we not escape, if we turn away from him that speaks from heaven:

Therefore the people did strive with Moses, and said, Give us water that we may drink. And Moses said unto them, Why do you strive with me? why do you test the LORD?

And he called the name of the place Massah, and Meribah, because of the striving of the children of Israel, and because they tempted the LORD, saying, Is the LORD among us, or not?

And the LORD said unto Moses, How long will this people despise me? and how long will it be before they believe me, with all the signs which I have shown among them?

Because all those men who have seen my glory, and my miracles, which I did in Egypt and in the wilderness, and have put me to the test now these ten times, and have not hearkened to my voice;

How long shall I bear with this evil congregation, which murmur against me? I have heard the murmurings of the children of Israel, which they murmur against me.

This is the water of Meribah, because the children of Israel strove with the LORD, and he was sanctified among them.

And the LORD heard the sound of your words, and was angry, and swore, saying,

Surely there shall not one of these men of this evil generation see that good land, which I swore to give unto your fathers,

You shall not test the LORD your God, as you tested him in Massah.

Harden not your hearts, as in the rebellion, in the day of testing in the wilderness:

When your fathers tested me, proved me, and saw my works forty years.

While it is said, Today if you will hear his voice, harden not your hearts, as in the provocation.

But with whom was he grieved forty years? was it not with them that had sinned, whose bodies fell in the wilderness?

So we see that they could not enter in because of unbelief.

I will therefore put you in remembrance, though you once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.
