משנה אויף ויקרא 4:2

If one says “A korban”, “A wholly burnt-offering”, “A meal-offering”, “A sin-offering”, “A thanksgiving-offering”, “A peace-offering, should be that which I eat from you” he is bound [by his vow]. Rabbi Judah permitted [him]. [If he says] “The korban”, “like a korban”, “korban”, should be that which I eat from you he is bound [by his vow]. If he says, “That which I shall not eat of yours should be a korban”, Rabbi Meir forbids [him]. If one says to his fellow, “Konam be my mouth which speaks with you”, “My hands which work for you” [or] “My feet which walk with you,’ he is forbidden.

There is no difference between a priest anointed with the oil of anointment and one who [only] wears the additional garments except for the bull which is offered for the [unwitting transgression of] any of the commandments. There is no difference between a serving [high] priest and one whose time has passed except the bull of Yom HaKippurim and the tenth of the ephah.
