Tafsiran Imamat 23:13: Rashi, Siftei Chakhamim, Chizkuni & Da'at Zekenim

ומנחתו AND THE MEAL OFFERING THEREOF — i. e. the usual meal-offering that was brought together with its drink-offering,

The meal-offering [which accompanies] its wineoffering. I.e., [this offering is] not the meal offering [which is brought] by itself that is mentioned in parshas Vayikra. Because iIt is written afterwards “Its wine-offering is one fourth of a hin,” and since the wine is [comes as] a wine-offering, the meal offering too is also certainly the mealoffering [which accompanies] a wine offering. Even though it is two tenths and the mealoffering of a sheep [that accompanies a wineoffering] is [generally] one [tenth], even so, it is [nevertheless] the meal-offering [which accompanies] a wine-offering, except that [here] it is double [the normal amount].

ומנחתו שני עשרונים סלת, and its gift offering, “two tenths of fine flour, etc.;” this was double the usual amount as it was the first offering presented from the new harvest. The additional amount of flour presented symbolizes that the harvest has been bountiful. Seeing that we do not find a parallel when it comes to the number of sheep offered on this occasion in addition to the breads, we mention in our mussaph prayers on the festival the respective components of each of these offerings. Some opinions hold that the one “tenth” of fine flour mentioned here was the “omer,” and they bring as proof that the libation accompanying that offering was not commensurate with the two “tenths” of fine flour mentioned here. This argument is without merit, as the two “tenths” mentioned here were wheat flour, whereas the “omer” consisted of barley. The expression סלת for finely ground flour is used exclusively with flour made from wheat.

שני עשרנים TWO TENTHS DEALS OF FLOUR — It was double as much as was usually required with a lamb (cf. Numbers ch. 28).

ונסכו רביעית ההין AND THE DRINK OFFERING THEREOF OF WINE SHALL BE THE FOURTH PART OF HIN — Although its meal-offering was twice as much as usual its drink-offering was not double (Menachot 89b).
