Jerome
Catena Aurea · Matthäusevangelium 6
Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal: But lay up for yourselves treasures in Heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal: For where your treasure is, there will your heart be also.
This must be understood not of money only, but of all our possessions. The god of a glutton is his belly; of a lover his lust; and so every man serves that to which he is in bondage; and has his heart there where his treasure is.
