What was significant about the dew of Hermon? (Psalm 133:3)

Psalm 133-134 New International Version (NIV)
Psalm 133
A song of ascents. Of David.
1 How good and pleasant it is
    when God’s people live together in unity!

2 It is like precious oil poured on the head,
    running down on the beard,
running down on Aaron’s beard,
    down on the collar of his robe.
3 It is as if the dew of Hermon
    were falling on Mount Zion.
For there the Lord bestows his blessing,
    even life forevermore.
