'Heart' in the Bible

See, O Yahweh, that {I am in distress}; {my stomach} is in torment, my heart has turned inside me because I have certainly rebelled. From outside a sword brings bereavement, inside the house [it is] like death.

Let all their evil come before you; and deal with them just as you have dealt with me because of all my crimes; for my groaning is much and my heart [is] faint.

My eyes have {spent all their tears}; {my stomach} is in torment, {my heart} is poured out on the earth because of the destruction of the daughter of my people, because child and babe faint in [the] public squares of a city.

Their heart cried to the Lord, "O wall of the daughter of Zion, let tears stream down like a river; day and night, do not give yourself relief, do not give your eyes rest.

"Arise, cry out in the night, at the beginning of the night watches; pour out your heart like water, before the face of the Lord. Lift to him your hands, for the life of your children, who faint in starvation, at the head of all streets."

Give them a stubborn heart; curse them!

Because of this, our heart has become faint, because of these, our eyes have become dim.
