Thou coveredst it with the deep; either,
1. In the general deluge. Or rather,
2. In the first creation, as we read, Genesis 1:2,9; of which the psalmist is here speaking. The waters stood above the mountains; the mountains were not made by the deluge, as some have thought, who for that reason understand this verse of the said deluge, for it is apparent they were before it, Genesis 7:19, and most probably were in the first creation, because this variety of mountains and valleys is both ornamental and useful to the world.
