'Abounding' in the Bible

But woe (judgment is coming) to you who are rich [and place your faith in possessions while remaining spiritually impoverished], for you are [already] receiving your comfort in full [and there is nothing left to be awarded to you].

The good man out of the good treasure of his heart doth bring forth that which is good; and the evil man out of the evil treasure of his heart doth bring forth that which is evil; for out of the abounding of the heart doth his mouth speak.
