Ps 105:15

“"And He gave them their desire, and sent fullness withal into their souls" [Psalm 106:15]. But He did not thus render them happy: for it was not that fullness of which it is said, "Blessed are they which do hunger and thirst after righteousness: for they shall be filled." [Matthew 5:6] In this passage he does not speak of the rational soul, but of the soul as giving animal life to the body; to the substance of which belong meat and drink, according to what is said in the Gospel, "Is not the soul more than meat, and the body than raiment?" [Matthew 6:26] as if it belonged to the soul to eat, to the body to be clothed.”
