Theodoret of Cyrus
What has embellished your feet in your sandals, O women of Nadavl? Simmachus translated it as the guide of the Leader, which refers to the Holy Spirit. "What is it that beautifies your feet?" He commends those whose feet are steadfast, who tread the righteous path, who radiate in their footwear. Isaiah, beholding the splendor of these feet, exclaimed: "Thy two breasts are like two fawns that are twins of a gazelle" (Song of Songs 7:4); "Thy eyes are like the pools in Heshbon, by the gate of Bath Rabbim: thy nose is like the tower of Lebanon which looketh toward Damascus" (Song of Songs 7:5); "Thy head upon thee is like Carmel, and the hair of thy head like purple; the king is held in the galleries" (Song of Songs 7:6). This conveys a slight divergence from what is articulated about the Bride in the subsequent verse (Song 4), thus requiring no further interpretation.
