'Harden' in the Bible

And Yahweh said to Moses, "When you go to return to Egypt, see all of the wonders that I have put in your hand, and do them before Pharaoh, and I myself will harden his heart, and he will not release the people.

And I myself will harden the heart of Pharaoh, and I will make my signs and my wonders numerous in the land of Egypt.

And I will harden the heart of Pharaoh, and he will chase after them, and I will be glorified through Pharaoh and through all his army, and [the] Egyptians will know that I [am] Yahweh." And they did so.

And as for me, look, I [am] about to harden the heart of [the] Egyptians [so that] they come after them, and I will display my glory through Pharaoh and through all of his army, through his chariots and through his charioteers.

If [there] is a poor [person] among you from [among] one of your brothers in one of your {towns} that Yahweh your God [is] giving to you, you shall not harden your heart, and you shall not shut your hand toward {your brother who is poor}.

Why should you harden your hearts like [the] Egyptians and Pharaoh hardened their heart? Is it not just like when he dealt with them wantonly so that they sent them away and they left?

"Do not harden your heart as [at] Meribah, as [in] the day of Massah in the wilderness,

Why do you make us wander, Yahweh? You harden our heart from your ways {so that we do not fear} you. Turn back for the sake of your servants, the tribes of your inheritance.

do not harden your hearts as in the rebellion, in the day of testing in the wilderness,

{while it is said}, "Today, if you hear his voice, do not harden your hearts as in the rebellion."

again he ordains a certain day, today, speaking by David after so long a time, just as had been said before, "Today, if you hear his voice, do not harden your hearts."
