For with you is the fountain of life; in your light do we see light.
Psalm 36 Almost all interpreters agree in supposing, that in this psalm David in general expresses his wonder and amazement at the goodness of God, because, in the exercise of his favor and mercy, he bears with the wicked, who, notwithstanding, basely contemn him. The opinion which I have formed is somewhat different.
Commenting on Psalm 36:1-12
From the baseness of the wicked the psalmist turns his contemplation to the glory of God. Contrasts are impressive.
Commenting on Psalm 36:5
For with thee is the fountain of life. This verse is made of simple words, but like the first chapter of John's Gospel, it is very deep. From the Lord, as from an independent self sufficient spring, all creature life proceeds, by him is sustained, through him alone can it be perfected. Life is in the creature, but the fountain of it is only in the Creator.
