Charles Ellicott Commentary Matthew 6:19

"Lay not up for yourselves treasures upon the earth, where moth and rust consume, and where thieves break through and steal:" — Matthew 6:19 (ASV)

Lay not up for yourselves treasures—Literally, with a force that the English lacks, treasure not up your treasures.

Where moth and rust doth corrupt—The first word points to one form of Eastern wealth: the costly garments of rich material, often embroidered with gold and silver (compare Your garments are moth-eaten in James 5:2). The second word is not so much the specific “rust” of metals as the decay that eats into and corrodes all the perishable goods of earth.
