Thou coverest it with the deep as with a garment
This refers not to the waters of the flood, when the earth was covered with them, even the tops of the highest mountains; but to the huge mass of waters, the abyss and depth of them, which lay upon the earth and covered it as a garment, at its first creation, as the context and the scope of it show; and which deep was covered with darkness, at which time the earth was without form, and void, ( Genesis 1:2 ) an emblem of the corrupt state of man by nature, destitute of the image of God, void and empty of all that is good, having an huge mass of sin and corruption on him, and being darkness itself; though this depth does not separate the elect of God, in this state, from his love; nor these aboundings of sin hinder the superaboundings of the grace of God; nor the operations of his Spirit; nor the communication of light unto them; nor the forming and renewing them, so as to become a curious piece of workmanship; even as the state of the original earth did not hinder the moving of the Spirit upon the waters that covered it, to the bringing of it into a beautiful form and order.
The waters stood above the mountains;
from whence we learn the mountains were from the beginning of the creation; since they were when the depths of water covered the unformed chaos; and which depths were so very great as to reach above the highest mountains; an emblem of the universal corruption of human nature; the highest, the greatest men that ever were, comparable to mountains, have been involved in it, as David, Paul, and others.
