Psalms 114:7

Tremble, thou earth, at the presence of the Lord ... - This is at the same time an explanation of the facts referred to in the previous verses, and the statement of an important truth in regard to the power of God. The true explanation - as here implied - of what occurred to the sea, to the Jordan, to the mountains, and to the hills, was the fact that God was there; the inference from that, or the truth which followed from that, was, that before that God in whose presence the very mountains shook, and from whom the waters of the sea fled in alarm the whole earth should tremble.
