Shir Hashirim Asher L'Shlomo. This is the work of Shlomo, the one man about whom it says that God loved (2 Shmuel 12:24). It's the realization of Malchut. It's the moon coming into its fullness, as expressed by the prophet's name for Shlomo - Yedidya - the yud-dalet - 14 - coming into yud-heh - 15 - the day of the moon's fullness and Shlomo being the 15th generation since Avraham. It was the climactic realization of the mission of shalom achicha that Yaakov sent Yosef on, making peace between the two dominant tribal energies of Yosef and Yehuda.
