Psalms 85, 102, 106, 123, 137
85 - The timing of the psalm may have been in the early years following the release of Israel from Persia, where some had returned to Israel, and many had stayed in the land of Cyrus. It’s a psalm of prayer and praise to God, Who is faithful, but Who also exercises justice. The final verses describe Jesus, Who is the marriage between mercy and truth, between righteousness and peace.
102 - A prayer of the afflicted who wait upon God for their relief and deliverance
106 - This is a recitation of Israel’s history in continuously being saved by God, and then turning around and rejecting Him, yet the mercy of God continues to respond when His people turn to Him in submission. He saves for His Name’s sake, and not for the sake of anyone’s righteousness or goodness.
123 - A cry for mercy from the Lord
137 - A song of mourning among those who were slaves in Babylon, who suddenly had fond memories of Zion and Jerusalem.
