Les Nombres 7:14 Références de la Michna : Mishnah Chagigah

Vessels that have been finished in purity require immersion [before they are used] for sacred things, but not [before they are used] for terumah. A vessel unites all its contents [for impurity] in the case of sacred things, but not in the case of terumah. Sacred things become invalid [by impurity] of a fourth degree, but terumah [only by impurity] of a third degree. In the case of terumah, if one hand of his hands became impure, the other remains clean, but in the case of sacred things, he must immerse both [hands], because the one hand defiles the other for sacred things but not for terumah.
