The Greek verb dioryssō means to dig through or break through a wall — the action of a burglar tunneling into a house, used by Jesus in His teaching on treasure and the heart.
Dioryssō appears in Matthew 6:19-20, one of Jesus' most penetrating teachings: 'Do not store up for yourselves treasures on earth, where moths and vermin destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where moths and vermin do not destroy, and where thieves do not break in and steal.' The contrast is between earthly treasure — always vulnerable to theft or decay — and heavenly treasure that is eternally secure. The word forces a question about where the heart is anchored.
