'Heart' in the Bible

Because they are kindled like an oven, their heart burns within them; all night their anger {smolders}, [in the] morning it blazes like a flaming fire.

They do not cry out to me from their heart, but they wail on their beds; because of grain and new wine they lacerate themselves; they depart from me.

Their heart is false; now they must bear [their] guilt. He himself will break down their altars; he will destroy their stone pillars.

How can I give you up, Ephraim? [How] can I hand you over, Israel? How can I make you like Admah? [How] can I treat you like Zeboiim? My heart is disturbed within me; {all} my compassions are aroused.

When I fed them, they were satisfied; they were satisfied and their heart was lifted up; therefore they forgot me.

I will attack them like a bear robbed of her offspring, and I will tear open the covering of their heart; there I will devour them like a lion, like an animal of the field would mutilate them.
