'Heart' in the Bible

Shall they not teach you, tell you, and utter words out of their heart?

God who is wise in heart, and mighty in strength: who has hardened himself against him, and prospered?

Yet you hid these things in your heart. I know that this is with you:

"If you set your heart aright, stretch out your hands toward him.

Why does your heart carry you away? Why do your eyes flash,

They conceive mischief, and bring forth iniquity. Their heart prepares deceit."

For you have hidden their heart from understanding, Therefore you shall not exalt them.

My days are past, my plans are broken off, as are the thoughts of my heart.

Whom I, even I, shall see on my side. My eyes shall see, and not as a stranger. "My heart is consumed within me.

Please receive instruction from his mouth, and lay up his words in your heart.

For God has made my heart faint. The Almighty has terrified me.

I hold fast to my righteousness, and will not let it go. My heart shall not reproach me so long as I live.

the blessing of him who was ready to perish came on me, and I caused the widow's heart to sing for joy.

My heart is troubled, and doesn't rest. Days of affliction have come on me.

if my step has turned out of the way, if my heart walked after my eyes, if any defilement has stuck to my hands,

"If my heart has been enticed to a woman, and I have laid wait at my neighbor's door,

if his heart hasn't blessed me, if he hasn't been warmed with my sheep's fleece;

and my heart has been secretly enticed, and my hand threw a kiss from my mouth,

if like Adam I have covered my transgressions, by hiding my iniquity in my heart,

My words shall utter the uprightness of my heart. That which my lips know they shall speak sincerely.

If he set his heart on himself, If he gathered to himself his spirit and his breath,

"But those who are godless in heart lay up anger. They don't cry for help when he binds them.

"Yes, at this my heart trembles, and is moved out of its place.

Therefore men revere him. He doesn't regard any who are wise of heart."

His heart is as firm as a stone, yes, firm as the lower millstone.
