'Heart' in the Bible

But when his heart was lifted up and his spirit became so proud that he behaved arrogantly, he was deposed from his royal throne and his glory was taken away from him.

He was also driven away from mankind, and his heart was made like that of beasts, and his dwelling place was with the wild donkeys. He was given grass to eat like cattle, and his body was drenched with the dew of heaven until he recognized that the Most High God is ruler over the realm of mankind and that He sets over it whomever He wishes.

Yet you, his son, Belshazzar, have not humbled your heart, even though you knew all this,

“And through his shrewdnessHe will cause deceit to succeed by his influence;And he will magnify himself in his heart,And he will destroy many while they are at ease.He will even oppose the Prince of princes,But he will be broken without human agency.

Then he said to me, “Do not be afraid, Daniel, for from the first day that you set your heart on understanding this and on humbling yourself before your God, your words were heard, and I have come in response to your words.

When the multitude is carried away, his heart will be lifted up, and he will cause tens of thousands to fall; yet he will not prevail.

Then he will return to his land with much plunder; but his heart will be set against the holy covenant, and he will take action and then return to his own land.
