Chapter 32 in Tehillim is about Teshuva. In this chapter, Dovid
shows us the advantages of Teshuva and his personal experiances in
Teshuva. In the second part of this chapter, Dovid exhorts us to do
Teshuva because it is the intelligent thing to do. Chapter 33 in
Tehillim is part of the Pesukay D'Zimra on Shabbos. In this chapter, we learn about thanking Hashem for the way He helps us in this world. In this chapter we see that there is a connection between thanking Hashem for His chesed in the creation of the world and the way that Hashem runs the events of the world. Chapter 34 in Tehillim is also part of the Pesukai D'Zimra of Shabbos. In this chapter, Dovid thanks Hashem for helping him escape from Achish the King of the Plishtim. We also see that the reason that Hashem helped Dovid was because Dovid had fear of Hashem. We also learn the basics what is fearing Hashem.
