'Heart' in the Bible

But as the Ark of the Covenant of the LORD approached the City of David, Saul's daughter Michal was peering out a window, watching King David dancing and cavorting around, and she despised him in her heart.

LORD, for the sake of your servant, and consistent with your heart, you have done all of these great things and are now making these great things known.

"Now as for you, my son Solomon, get to know the God of your father. Serve him with a sound heart and a devoted soul, because the LORD is searching every heart, every plan and thought. He will be found by you, assuming you are seeking him, but if you abandon him, he will abandon you forever.

Then the people rejoiced because they had given voluntarily, since with a devoted heart they had freely given to the LORD.

And I know, God, that it is you who searches the heart and you who finds pleasure in righteousness. With a righteous heart I have freely given all these things, and now I have seen all of these people of yours giving freely and joyfully to you!

granting to my son Solomon to keep with a devoted heart your commands, your decrees, and your statutes, carrying out all of them, and that he may build the Temple for which I have made the preparations.
