Book 3 ends with two laments. The first is personal with no hint of hope, and the second is corporate. With Psalm 89 there is hope because of God's steadfast love to Israel, especially with the king, but then the king sins, and God brings judgement. The Psalmist does not see the Lord's steadfast love, and he cries out, "How long?" "Remember" Yet, the Psalmist ends with "Blessed be the Lord forever! Amen & Amen." We have hope in the midst of the crisis.
