Kabbalah zu Tehillim 9:3

The members of the Yeshivah then stand before Him, saying, Master of the universe, You are called gracious and merciful. So, apply Your mercy on Your children! He said to them: 'Have I not created the world based upon love?' As it is written, "For I have said, the world is built by love" (Ps. 89:3). So the whole universe is established upon it. The heavenly angels then say to Him, Master of the universe, there is a certain person who has eaten and drunk to his fill and could have been kind to the poor, but did not share with them anything! Then the "Accuser" comes and obtains permission to persecute that person.
