'Heart' in the Bible

The Lord regretted that He had made mankind on the earth, and He was [deeply] grieved in His heart.

The Lord smelled the pleasing aroma [a soothing, satisfying scent] and the Lord said to Himself, “I will never again curse the ground because of man, for the intent (strong inclination, desire) of man’s heart is wicked from his youth; and I will never again destroy every living thing, as I have done.

Then Abraham fell on his face and laughed, and said in his heart, “Shall a child be born to a man who is a hundred years old? And shall Sarah, who is ninety years old, bear a child?”

Did Abraham not tell me, ‘She is my sister?’ And she herself said, ‘He is my brother.’ In the integrity of my heart and innocence of my hands I have done this.”

Then God said to him in the dream, “Yes, I know you did this in the integrity of your heart, for it was I who kept you back and spared you from sinning against Me; therefore I did not give you an opportunity to touch her.

“Before I had finished praying in my heart, behold, Rebekah came out with her [water] jar on her shoulder, and she went down to the spring and drew water. And I said to her, ‘Please, let me have a drink.’

So Esau hated Jacob because of the blessing with which his father blessed him; and Esau said in his heart, “The days of mourning for my father are very near; then I will kill my brother Jacob.”

Then Joseph hurried out [of the room] because his heart was deeply touched over his brother, and he sought privacy to weep; so he entered his chamber and wept there.

and they said to him, “Joseph is still alive, and indeed he is ruler over all the land of Egypt.” But Jacob was stunned and his heart almost stopped beating, because he did not believe them.
