Charles H. Spurgeon on Psalms 133:3

Dew of Hermon. We had sensible proof at Rasheiya of the copiousness of the "dew of Hermon", spoken of in Ps 133:3, where "Zion" is only another name for the same mountain. Unlike most other mountains which gradually rise from lofty table lands and often at a distance from the sea, Hermon starts at once to the height of nearly ten thousand feet, from a platform scarcely above the sea level. This platform, too —the upper Jordan valley, and marshes of Merom —is for the most part an impenetrable swamp of unknown depth, whence the seething vapour, under the rays of an almost tropical sun, is constantly ascending into the upper atmosphere during the day. The vapour, coming in contact with the snowy sides of the mountain, is rapidly congealed, and is precipitated in the evening in the form of a dew, the most copious we ever experienced. It penetrated everywhere, and saturated everything. The floor of our tent was soaked, our bed was covered with it, our guns were dripping, and dewdrops hung about everywhere. No wonder that the foot of Hermon is clad with orchards and gardens of such marvellous fertility in this land of droughts. —Henry Baker Tristram, 1867.
