Charles H. Spurgeon on Psalms 123:3

We are exceedingly filled with contempt. Men of the world regard the Temple Pilgrims and their religion with the quiet smile of disdain, wondering that those who have so much to engage them in a present life should be weak enough to concern themselves about frames and feelings, about an unseen God, and unknown eternity; and this is a trial they find it hard to bear. Their soul, too, is filled exceedingly with the scorning of those that are at ease. The prosperous of their neighbours declare that they have found the world a generous and happy scene to all who deserve its gifts. Poverty and sorrow they attribute to unworthiness alone. "Let them exert themselves" is the unfeeling cry; "let them bestir themselves instead of praying, and with them as with us it will soon be well"; and these words of harsh and unfeeling ignorance aye like poison to the wounds of the bleeding heart. They have further "the contempt of the proud" to mourn; of those who give expression to their fierce disdain by assailing them with words of contumely, and who seek to draw them by reproaches both from peace and from piety. These are still the trials of Zion's worshippers: silent contempt, open misrepresentation, fierce opposition. Religion, their last comfort, is despised; peace, their first desire, is denied. Anxious to devote themselves in the spirit of humble and earnest piety to the duties of their appointed sphere, they find enemies in open outcry and array against them. But God is their refuge, and to him they go. —Robert Nisbet.

Verses 3,4. The second strophe takes up the "have mercy upon us, " as it were in echo. It begins with a "Kyrie eleison", which is confirmed in a crescendo manner after the form of steps. —Franz Delitszch.
