Yechezkel 44:30-31

Orthodox Jewish Bible

³⁰ And the reshit kol bikkurim of all things, and every terumah of all, of every sort of your terumot, shall belong to the Kohanim; ye shall also give unto the Kohen the reshit of your dough, that he may cause the brocha to rest on thine bais.

³¹ The Kohanim shall not eat of any thing nevelah, or terefah, whether it be oph or behemah.
