Haggai 2:13
Then Haggai said, 'If one who is unclean by contact with a dead body touches any of these, does it become unclean?' The priests answered, 'It becomes unclean'—the contrast is striking: whereas holiness does not transmit through contact, uncleanness (defilement) does. This asymmetry becomes the hinge of the prophecy's moral: uncleanness spreads readily while holiness must be actively established.
