Song of Songs Rabbah 2:6

¹“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. 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). 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. ; 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.”
