פּירוש אויף שיר השירים 4:13

Your arid fields. Dry land is called בֵּית הַשְּׁלָחִין [=thirsty land], and it necessary to irrigate it constantly; a field watered by rain [=בֵּית הַבַּעַל is superior to it.⁶³The Mishnah in Bava Basra describes בית הבעל as a field in the valley that is moist and does not require irrigation. (Sifsei Chachomim) Here he praises the arid field, “Your arid fields” are replete with all good like a pomegranate orchard. This is said of the smallest of Yisroel, who are succulent with good deeds like a pomegranate orchard.

Your limbs are an orchard of pomegranates And of all luscious fruits…. Solomon mentions here [Cant. 4:14] the twelve types of spices, corresponding to the twelve channels of the Holy One, blessed be He, through which the fragrance of divine Wisdom spreads forth and is directed towards the Patriarchs.

Henna with spikenard. These are types of spices.
