'Heart' in the Bible

“See, O Lord, for I am in distress;My spirit is greatly troubled;My heart is overturned within me,For I have been very rebellious.In the street the sword slays;In the house it is like death.

“Let all their wickedness come before You;And deal with them as You have dealt with meFor all my transgressions;For my groans are many and my heart is faint.”

My eyes fail because of tears,My spirit is greatly troubled;My heart is poured out on the earthBecause of the destruction of the daughter of my people,When little ones and infants faintIn the streets of the city.

Their heart cried out to the Lord,“O wall of the daughter of Zion,Let your tears run down like a river day and night;Give yourself no relief,Let your eyes have no rest.

“Arise, cry aloud in the nightAt the beginning of the night watches;Pour out your heart like waterBefore the presence of the Lord;Lift up your hands to HimFor the life of your little onesWho are faint because of hungerAt the head of every street.”

We lift up our heart and handsToward God in heaven;

You will give them hardness of heart,Your curse will be on them.

Because of this our heart is faint,Because of these things our eyes are dim;
