It is like the dew of Hermon that is descending upon the mountains of Zion. For there Jehovah commanded the blessing to be, even life to time indefinite.”​—Ps. 133:1-3.

When all the tribes of Israel would come to Jerusalem for the three annual festivals, they had the opportunity to dwell together in unity.

Israel’s dwelling together in unity was also like the dew of Mount Hermon. That mountain, having an elevation of over 9,000 feet (2,700 m) above sea level, is snowcapped nearly the year around. Hermon’s snowy top serves to condense the night vapors and in this way produces the abundant dew that preserves vegetation during the long dry season. Cold air currents from the Hermon range can also carry the vapors as far south as Mount Zion, there to condense as dew. So the psalmist correctly spoke of the ‘dew of Hermon as descending upon Mount Zion.’ The picture is of a descending influence, a refreshing influence, that contributes toward the preservation of vegetation.

The unity of Christian brothers is just as delightful. It, too, has life-preserving potential. This is so because, when observing the love existing among God’s true servants today, many persons begin to wonder about the source of this unity. Their investigation then gets them started on the way leading to life.
