Charles H. Spurgeon on Psalms 18:15

"The foundations of the world were discovered;" i.e., such large and deep chasms, or apertures, were made by the violence of the earthquake, as one might almost see the very foundations, or as Jonah calls them, the bottoms, or rather, the extremities of the mountains, in the bottom of the sea. Jonah 2:6. —Samuel Chandler.
