Then the channels of waters were seen, and the foundations of the world were discovered at thy rebuke, O LORD, at the blast of the breath of thy nostrils. The channels of water were seen - This must refer to an earthquake; for in such cases, the ground being rent, water frequently gushes out at the fissures, and often rises to a tremendous height. Whole rivers were poured out of the chasms made by the earthquake in Jamaica, A. D. 1694; and new lakes of water were formed, covering a thousand acres of land!
