'Heart's' in the Bible

You may spend the money to your heart's content to buy livestock, flocks, wine, strong drink, and whatever you desire. You and your household may eat there and rejoice in the presence of the LORD your God."

After Boaz had finished eating and drinking to his heart's content, he went over and lay down next to the pile of threshed grain. Ruth came in quietly, uncovered his feet, and lay down.

My days are passed; my plans have been shattered; along with my heart's desires.

I am weak and utterly crushed; I cry out in distress because of my heart's anguish.

A righteous person eats to his heart's content, but the stomach of the wicked remains hungry.

a man to whom God gives wealth, riches, and honor, so that he lacks none of his heart's desires but God does not give him the capability to enjoy them. Instead, a stranger consumes them. This is pointless and a grievous affliction.

So repent of this wickedness of yours, and pray to the Lord that, if possible, your heart's intent may be forgiven you.

Brothers, my heart's desire and prayer to God about the Jews is that they would be saved.
