What does Psalms Chapter 106 say, and which statements belong to its speaker?

Confitemini Domino and Alleluia introduce the heading's thanksgiving for perpetual providence. Redeemed people gathered from countries, sun's rising and setting, north and sea are to glory in God's enduring mercy. Waterless wilderness wanderers lacked city path, hungry and thirsty with fainting souls. They cried and were delivered and guided a right way toward habitation. The refrain calls mercies and works to glory, with empty and hungry souls satisfied.

Those in darkness and death's shadow were bound in want and iron because they exasperated words and counsel, humbled with labor and weakened without help. Crying brought delivery, darkness lifted and bonds broken, with the refrain and brass gates and iron bars broken. Others were taken out of iniquity and brought low for injustice, abhorred food and approached death's gates; cries brought delivery, a sent word healed and rescued. The source does not name fools or supply a particular disease. Praise sacrifice and joyful works declaration follow.

Shipboard business people saw deep wonders; a spoken word brought windstorm and high waves. They mounted to heaven and down depths, souls pined, reeling like drunken men and wisdom swallowed. Crying brought delivery, storm became breeze and waves still; they rejoiced and reached desired haven. The repeated glory call includes church of people and chair of ancients. No particular navigation maneuver is described.

Rivers and water sources became dry wilderness and fertile land barren for inhabitants' wickedness. Wilderness became pools and springs, hungry people placed and building a city, sowing fields and vineyards yielding fruit. They multiplied under blessing, cattle not decreased. Then they became few and afflicted through evils and sorrow, contempt upon princes wandering impassable ways. Poor people were helped from poverty and families made like sheep. The just shall see and rejoice and iniquity stop her mouth, ending a question about wisdom, keeping and understanding mercies. Population decline is retained, princes are not newly called tyrants and cattle preservation is not changed to multiplication.
