Charles H. Spurgeon on Psalms 18:7

The volcanic phenomena of Palestine open a question of which the data are, in a scientific point of view, too imperfect to be discussed; but there is enough in the history and literature of the people to show that there was an agency of this kind at work. The valley of the Jordan, both in its desolation and vegetation, was one continued portent; and from its crevices ramified even into the interior of Judea the startling appearances, if not of the volcano, at least of the earthquake. Their historical effect in the special theatres of their operation will appear as we proceed; but their traces on the permanent feeling of the nation must be noticed here. The writings of the psalmists and prophets abound with indications which escape the eye of a superficial reader. Like the soil of their country, they actually heave and labour with the fiery convulsions which glow beneath their surface. —Arthur Penrhyn Stanley.
