This song, marks another stage in the approach of the worshiper in that it sets forth his assurance of the present help of The LORD. The singer is still far from the appointed place of worship, lifting his eyes toward the distant mountains. He is not far from God, however, even though far from the center of external worship, the pilgrim realizes his safety. He lifts his longing eyes toward the mountains of Zion, where stands the house of his God
Not from those mountains, precious as they are, but from The LORD, who is with him even in the valley of distance. He then addresses the singer's heart with words of comfort and assurance. God keeps His children safe, never slumbering or sleeping in His faithful vigil.
The stately sentences which describe the tender care of God are the common language of all who know The LORD. These Psalms, prepare for the outburst of the next song for approach to the place of worship as the day dawns.
