An examination of the passages in Ezekiel related to the 'defilement' and 'desecration' of the Temple through the spectrum of the Priestly Sources clearly shows a distinction between the two concepts and reveals Ezekiel’s precise and deliberate usage of these terms. Although they both relate to idolatrous practices, defilement of the Temple in Ezekiel follows the categories of the Priestly Sources, and thus results primarily from corpse impurity and idol worship. With regard to the Temple’s desecration, Ezekiel introduces the aspect of the intense involvement of foreigners, which he viewed as the desecrating agents of his day.
