Reference for Zevachim 38:19

מאי טעמא דרבי דכתיב (שמות ל, כ) בגשתם מ"ט דרבי אלעזר בר"ש דכתיב (שמות ל, כ) בבואם

R'Eleazar son of R'Simeon said: The passing of the night is not effective in respect of the sanctification of hands and feet. Another [Baraitha] taught: If [a priest] was standing and offering [the fats] on the altar throughout the night, at dawn he needs sanctification of hands and feet: this is Rabbi's view.
