'Heart' in the Bible

See, O Lord, for I am in trouble; the inmost parts of my body are deeply moved; my heart is turned in me; for I have been uncontrolled: outside the children are put to the sword, and in the house there is death.

Let all their evil-doing come before you; do to them as you have done to me for all my sins: for loud is the sound of my grief, and the strength of my heart is gone.

Up! give cries in the night, at the starting of the night-watches; let your heart be flowing out like water before the face of the Lord, lifting up your hands to him for the life of your young children who are falling down, feeble for need of food, at the top of every street.
