'Hearts' in the Bible

and all of the people were evil Ephraim and the inhabitants of Samaria saying proudly with arrogant hearts:

A message about Egypt: "Watch out! The LORD rides on a swift cloud, and is coming to Egypt. The idols of Egypt tremble before him, and the hearts of the Egyptians melt within them.

Then the Lord said: "Because these people draw near with their mouths and honor me with their lips, but their hearts are far from me, worship of me has become merely like rules taught by human beings.

The hearts of reckless people will understand sound judgment, and the tongues of those who stammer will be ready to speak clearly.

Say to those with anxious hearts, "Be strong, do not be afraid! Here is your God he will bring vengeance, he will bring divine retribution, and he will save you.'

Listen to me, you who know righteousness, you people who have my instruction in their hearts. Don't fear the insults of mortals, and don't be dismayed at their hateful words.

Why, LORD, do you make us wander from your ways and harden our hearts, so that we do not fear you? Turn back for the sake of your servants, for the sake of the tribes that are your heritage.

And when you look, your hearts will rejoice and your bodies will flourish like grass; and it will be made known that the LORD's hand is with his servants, but his fury is with his enemies.
