Rashi on Leviticus 23:37/רש"י על ויקרא כ״ג:ל״ז

1עלה ומנחה A BURNT OFFERING AND A MEAL OFFERING — This means the מנחת נסכים (the meal-offering due with the drink-offering) that is brought together with the‎ עולה (Menachot 44b)‎.

2‎‎ביומו‎ ‎יום‎ ‎דבר EVERYTHING UPON ITS DAY (lit., the thing of the day, on its day) — the quantity definitely assigned to each day in the Book of Numbers (cf. Rashi on Exodus 16:4).

3דבר יום ביומו EVERYTHING UPON ITS DAY (which may mean the matter of the day shall be on its day) — consequently if its day (the day on which some particular one of these sacrifices is due) be past, it's (the day’s) offering is past (cf. Sifra, Emor, Section 12 9).
