And these are the [things] that are burned: Cha-metz on Pesach is burned, and [so is] terumah that is tamei, and [fruits of] orlah, and kilayim of the vineyard. That which it is usual to burn is burned, and that which it is usual to bury is buried. And [the Kohanim] may kindle [a fire] with bread or oil of terumah.
