A fountain of gardens, a well of living waters, and streams from Lebanon.
A fountain of gardens, a well of living waters - "of." This pleasure-ground is not dependent on mere reservoirs; it has a fountain sufficient to water many "gardens," (plur.)
Living - (Jeremiah 2:13; Jeremiah 17:8; John 4:13-14.)
Streams from Lebanon - though the fountain is lowly, the source is lofty; fed by the perpetual snows of Lebanon, refreshingly cool (Jeremiah 18:14), fertilizing the gardens of Damascus. It springs open earth; its source is heaven. It is now not "sealed," but open "streams" (Revelation 22:17).
