Theodoret of Cyrus
What embellishes your feet in your sandals, O women of Nadavl? Simmachus interpreted it as the "dshchi of the Leader," referring to the Holy Spirit. “What beautifies your feet?” He commends the feet that are steadfast, that tread the righteous path, that radiate in their sandals. Isaiah, captivated by the beauty of these feet, proclaimed: “Thy two teats are as two young twins of the chamois” (Song of Songs 7:4); “Thy eyes are as an elephant's pillar; thy eyes are as lakes in Heshbon, in the gates of the daughters of many; thy nose is as a pillar of Lebanon, looking towards the face of Damascus” (Song of Songs 7:5); “Thy head is upon thee as Carmel, and the braiding of thy head as scarlet; the king is bound in thrones” (Song of Songs 7:6). This language varies slightly from the descriptions of the Bride in the second verse (Song 4), and thus further explanation is unnecessary.
