Blessed are they who do hunger and thirst after righteousness: for they shall be filled.
All Commentaries on Matthew 5:6 Go To Matthew 5
Augustine of Hippo
Now He calls those parties, lovers of a true and indestructible good. They will therefore be filled with that food of which the Lord Himself says, My meat is to do the will of my Father, which is righteousness; and with that water, of which whosoever drinks, as he also says, it shall be in him a well of water, springing up into everlasting life.
