Psalms 77:7

Will the Lord cast off for ever? - Will there be no end to this captivity? Has he not said, "Turn, ye backsliders; for I am married unto you: I will heal your backsliding, and love you freely." Will he then be favorable no more? Thus the psalmist pleads and reasons with his Maker.

Will the Lord cast off for ever? - This was the subject, and the substance, of his inquiry: whether it was a fair and just conclusion that God would show no mercy; would never be gracious again. Evidently the thought passed through his mind that this seemed to be the character of God; that things looked as if this were so; that it was difficult, if not impossible, to understand the divine dealings otherwise; and he asks whether this was a fair conclusion; whether he must be constrained to believe that this was so.

And will he be favorable no more? - Will he no more show favor to people? Will he pardon and save no more of the race of mankind?

77:7 Cut off - His peculiar people.
