Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
Psalm 114 is of the highest style of poetry, but is important to us as directly connecting the ancient deliverance of Israel out of Egypt with the present deliverance of the people, and seeing the same Jehovah in both calling the earth to tremble at the presence of Jehovah. It was right in those days. At Jacob's deliverance then, the sea fled and Jordan was driven back. What was this? Was it affright before the presence of man? The earth was now to tremble before Him who appeared for the deliverance of His people then, and for their sakes turned the sea into dry land, and the flint stone into a springing well.
