Matthew Poole and continuators on Song of Solomon 4:15

15 A fountain of gardens, a well of living waters , and streams from Lebanon .

These are the words either 1. Of the Bride, who returns this Answer to the Bridegroom. Thou callest me a Fountain, but in truth thou only art that Fountain from whence I derive all my streams of comfort: Or rather 2. Of the Bridegroom, who hath hitherto been speaking to and of the Church, and still continues his Speech. He seems to add this by way of correction to, or exposition of what he said v. 12. Though my Spouse be in some sort a Fountain shut up or sealed, yet that is not so to be understood as if she kept her Waters to her self, for she is like a Fountain or Well of living or running water, which floweth into Gardens, and maketh its Flowers and Plants to grow and flourish. The Church conveyeth those Waters of Life which she receiveth from Christ unto particular Believers and Congregations.

Like those sweet and refreshing Rivers which flow down from Mount Lebanon, of which Iordan is one.
