Thou art a fountain of gardens, A well of living waters, And flowing streams from Lebanon.
Rashi on Song of Songs
You are a garden spring. All this refers back to, “Your arid fields,” and he praises them like a fountain which irrigates them. The allegory is: It refers to the immersions of purification which the daughters of Yisroel immerse themselves.
Rashi on Song of Songs
And flowing streams from Levanon. From a place of cleanliness, without the murkiness of mud.
