Comentario citado sobre Números 28:12

ומנחתם ונסכיהם WITH THEIR MEAL OFFERINGS AND THEIR DRINK OFFERINGS — according to the law of the meal offerings and the drink offerings which are distinctly set forth with reference to all animal sacrifices in the chapter dealing with drink offerings: (Numbers 28:12—14) “three tenth deals of flour for one bullock, two tenth deals of flour for one ram, and one tenth deal of flour for one lamb”: — this is the meal-offering. The drink-offerings were: “half a hin of wine for a bullock, the third part of a hin of wine for a ram, and the fourth part of a hin of wine for a lamb”.

The other seven garments symbolized the seven heavens; I will explain this in greater detail at the end of Parshat Tzav (Leviticus 8,7). The golden head-plate represented the highest of all the heavens. The very words inscribed on the head-plate are an allusion to the principle that the glory of the princess is best seen by the fact that she stays out of the limelight, as Psalms 45,14 phrased it כל כבודה בת מלך פנימה ממשבצות זהב לבושה, “the royal princess, her dress embroidered with golden mountings, (is led inside to the king.”) The chamber (heaven) referred to is the tenth, innermost. This is why the ציץ was made of pure gold and why it was appropriately inscribed with the words קדש לה'. This is also the meaning of the words פתוחי חותם קדש לה', “engraved like a signet ring ‘holy unto the Lord.’” The Torah writes in verse 38 that the ציץ is to be worn on Aaron’s forehead, and that it is to be on his forehead תמיד “always.” How are we to understand the latter word “always?” The word refers to the periods during which the High Priests fulfills his specific functions in the Temple or within the holy precincts. As you are already aware the High Priest served as a symbol and so did his vestments while he wore them during the performance of his duties. This is the reason why the Torah wrote the word לזכרון, “as a remembrance,” i.e. as a symbol, in connection with the gemstones on the ephod and with the gemstones on the breastplate (compare verse 12 and verse 29). The word לזכרון is very close in meaning to the word לדוגמה, “as an example, a model, a symbol.” The word ציץ itself is reminiscent of Song of Songs 2,9 מציץ מן החרכים, “He was peering through the lattices.” Aaron’s inspiration came from the Shechinah which peered through the lattices (shuttered windows of the highest heaven) observing him performing his functions. The word is related to ויצץ ציץ, “it sprouted a bud,” i.e. the topmost part of the fruit. Wherever the word occurs it alludes to the highest of something. Just as this particular ornament symbolized the highest emanation, the highest attribute of G’d, so all the vestments symbolized something of that nature.
