This Psalm shares ways that The Lord redeemed His people.
Verses 6, 13, 19, and 28 all share the exact same words. Right after sharing a way that the people of God were in distress each verse reads: then they cried out to The Lord in their trouble, and he delivered them from their distress.
Four times in one Psalm. Seems important hey?
Following each of these comes another piece of repition (verses 8, 15, 21, 31): Let them thank The Lord for his steadfast love, for his wondeous works to the children of man!
Four times? Seems important.
Repition is important. I think this Psalm is given to show that God is continuous in His faithful redemption.
The Psalm ends this way (v. 43):
Whoever is wise, let him attend to these things; let them consider the steadfast love of The Lord.
