Commentary for Megillah 23:17

Just as the law of the Torah: The food of the altar is greater than the drink - a bull and three isaron of fine flour for food; but the libation is [only] half a hin.

Just as the law of the Torah, the food is greater than the drink: And [regarding] that which we say in Niddah 24b, "The bones of anyone who eats more than he drinks are black" - that is when he eats more than enough.
