Comentario sobre Levítico 9:23

ויבא משה ואהרן AND MOSES AND AARON CAME, etc. — Wherefore did they now enter the Tabernacle? I have found the following in the “Mechilta d’Miluim,” in the Boraitha that is appended to our Torath Cohanim (Sifra): Wherefore did Moses enter with Aaron? To instruct him regarding the incense ceremony. Or it may be that he entered for some other reason?! See, I draw a conclusion: the descent from the altar and the entry into the tent of meeting both required to be accompanied by a benediction, as stated in vv. 22 and 23 (and consequently both were, in a measure, of similar character). Now what was the descent from the altar? It was of the nature (it look place in connection with) a sacrificial act! So, also, the entry into the tent took place in connection with a sacrificial act! Thus you may learn: Why did Moses enter with Aaron? To instruct him regarding the incense ceremony which was the only rite performed on that day within the tent! (Cf. Talmud Yerushalmi Taanit 4). Another explanation is: When Aaron perceived that all the sacrifices had been offered and all the rites performed, and yet the Shechinah had not descended for Israel, since the heavenly fire had not fallen to consume the sacrifice, he was uneasy in mind and said: I feel certain that the Holy One, blessed be He, is angry with me and that it is on my account that the Shechinah has not descended for Israel. He therefore said to Moses: “My brother Moses! Do you act thus with me: you know that I have entered into this matter at your bidding and yet I have been put to shame! Moses at once entered the tent with him and they offered prayer and the Shechinah descended for Israel (Sifra, Shemini, Mechilta d'Miluim 2 18).

ויצאו ויברכו את העם, They emerged from the Tabernacle and blessed the people. Perhaps they had been commanded to do so by a prophetic vision. It is also possible that the Torah substitutes the word "blessing" here for the word "prayer." The prayer may have been that G'd's Presence should continue to manifest itself in the camp. Even though the people had already been blessed by Aaron, it was good to be blessed by both brothers each of whom represented a different nuance of spirituality, one that is unique to the Levite and the other the spirituality unique to the priesthood. In kabbalistic terms the two brothers Aaron and Moses represented the emanations חסד וגבורה respectively.
