19You shall offer up a fire offering, a burnt offering to the Lord: two young bulls, one ram, and seven lambs in the first year they shall be unblemished for you.
ram: Symbolizing the ram [sacrificed instead] of Isaac (see Gen. 22:13).
אילים:
כְּנֶגֶד אֵילוֹ שֶׁל יִצְחָק:
lambs: Corresponding to Jacob, of whom it says, “Jacob separated the lambs” (Gen. 30:40). I saw this in the commentary of R. Moshe Hadarshan [the preacher]. - [Mid. Aggadah, Midrash Tadshey ch. 10]
24Like these, you shall offer up daily for seven days, food of the fire offering, a spirit of satisfaction to the Lord; you shall offer up this in addition to the continual burnt offering and its libation.
Like these, you shall offer up daily: They should not be decreased progressively, as is the case of the bulls of the [Sukkoth] festival. — [Sifrei Pinchas 48]
