The antithetical nature of this psalm is self-evident. In the first part (verses Psa 36:1-4), the reason and expression of the wickedness of the wicked are described. The one and only reason for transgression is that the fear of God is lost. All evil results therefrom.
In contrast to this the advantages of the remembrance of Jehovah are set forth, first, by a description of certain facts concerning Him. One can easily imagine that the psalm was written on some natural height from which the singer looked out on a far-stretching scene in which he saw symbols of truth concerning his God. Note the sweep of vision. The heavens, the skies or clouds, the mountains, the great deep, the river, and, over all, the light.
There is a fine fitness in the interpretation of suggestiveness. The encompassing blue speaks of lovingkindness; the passing clouds in the mystery of their orderliness, of His faithfulness; the mountains suggest His righteousness from which rivers of pleasure flow to mingle in the deep of His judgments. Of all the abundant and varying life He is the Source or Fountain and the sunshine of His face is the light on everything. All ends with a prayer for the continued safety of the divine care and protection.
