John Chrysostom
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.
Saying, Lay not up for yourselves treasure on earth, He adds, where rust and moth destroy, in order to shew the insecurity of that treasure that is here, and the advantage of that which is in Heaven, both from the place, and from those things which harm. As though He had said; Why fear you that your wealth should be consumed, if you should give alms? Yea rather give alms, and they shall receive increase, for those treasures that are in Heaven shall be added to them, which treasures perish if ye do not give alms. He said not, You leave them to others, for that is pleasant to men.
