'Heart' in the Bible

Look, LORD, how distressed I am; all my insides are churning. My heart is troubled within me, because I vigorously rebelled. Outside the sword brings loss of life, while at home death rules.

May all of their wickedness come to your attention, and deal with them as you have done with me because of all my transgressions. For I am constantly groaning, and my heart is faint.

Cry out from your heart to the Lord, wall of fair Zion! Let your tears run down like a river day and night. Allow yourself no rest, and don't stop crying.

Get up and cry aloud in the night, at the beginning of every hour. Pour out your heart like water in the presence of the Lord! Lift up your hands toward him for the lives of your children, who are fainting away at every street corner.

Give them an anguished heart; may your curse be upon them!
