Midrash su Deuteronomio 11:22

Similarly, Moses declared: For if ye shall diligently guard (Deut. 11:22); that is, if you guard diligently the students of Torah, then you shall be guarded in turn. Hence Scripture states: For them that honor Me I will honor, and they that despise Me shall be lightly esteemed (I Sam. 2:30). This verse alludes to those who honor the students of the Torah.

Told and retold generation after generation, the Midrashim brought purpose, direction, and hope to the lives of the Jews, helping them to endure whatever trials they experienced. The Midrashim served as a balm for their aching hearts by making the concept of the world-to-come and the blessing it would bring a reality for them. The Sifré summarizes the ultimate goal and purpose of the Midrash when it tells us: “If you desire to know Him who spoke and the world came into being, learn the Aggadah, for from it you will come to know the Holy One, blessed be He, and cling to His ways.”¹Sifré on Deuteronomy 11:22.

“His left is under my head and his right embraces me” (Song of Songs 2:6).
“His left is under my head,” these are the first tablets; “and his right embraces me,” these are the second tablets. Alternatively, “his left is under my head,” these are ritual fringes; “and his right embraces me,” these are phylacteries. Alternatively, “his left is under my head” this is the reciting of Shema; and his right embraces me,” this is the Amida prayer. Alternatively, “his left is under my head,” this is sukka; “and his right embraces me,” this is the cloud of the Divine Presence in the future. That is what is written: “The sun will no longer be for you the light of day and the glow of the moon will not illuminate for you” (Isaiah 60:19). Who illuminates for you? “The Lord will be for you an eternal light” (Isaiah 60:19). Alternatively, “his left is under my head,” this is mezuza.” Rabbi Shimon ben Yoḥai taught: “You shall write them on the doorposts of your house” (Deuteronomy 6:9), when you enter from the marketplace to your house.⁷⁷It is on the right of the person entering the house, which is the left of the person exiting.
Rabbi Yoḥanan said: It is written: “You shall position the table outside the curtain [and the candelabrum opposite the table, on the side of the Tabernacle toward the south; and you shall put the table on the north side]” (Exodus 26:35).⁷⁸Since the Divine Presence emanated from the Holy of Holies, the candelabrum was to its right and the table was to its left. But that is not the case; a person places a candelabrum on the left so it will not restrict the right. A person does not place the left under the head and embrace with the right.⁷⁹The unusual placement of the candelabrum and the table reflect the fact that God’s embrace of Israel is not, as it were, for His comfort, but rather in order to support them (Midrash HaMevoar; cf. Matnot Kehuna).
Rabbi Aḥa said: Rabbi Yoḥanan cites it from this verse: “To love the Lord your God…and to cleave to Him” (Deuteronomy 30:20). What is this cleaving? “His left is under my head.”
