Charles H. Spurgeon on Psalms 118:5

Perhaps Ps 118:5, which says, I called upon the LORD in distress (literally, out of the narrow gorge), and the LORD answered me on the open plain —which describes the deliverance of Israel from their captivity, —may have been sung as they defiled from a narrow ravine into the plain; and when they arrived at the gate of the temple, then they broke forth in full chorus into the words, "Open to me the gates of righteousness" (Ps 118:19). Christopher Wordsworth.
