Lay not up for yourselves treasures upon earth,.... Meaning either treasures that are of an earthly nature and kind, the more valuable and excellent things of the earth, worldly wealth and riches; or the things and places, in which these are laid up, as bags, chests, or coffers, barns and other treasuries, private or public.
Christ here dissuades from covetousness, and worldly mindedness; an anxious care and concern, to hoard up plenty of worldly things for themselves, for time to come, making no use of them at present for the good of others: and this he does, from the nature of the things themselves; the places where they are laid up; the difficulty of keeping them; and their liableness to be corrupted or lost.
Where moth and rust doth corrupt, and thieves break through and steal.
