In numerous psalms, praise takes the form of narrating the Lord’s mighty acts of salvation. These psalms are often called “salva- tion history psalms” or “historical psalms.” Some appeal to God’s people, telling them to learn from their history, particularly from their and their ancestors’ mistakes. Certain historical psalms contain a pre-dominant hymnal note that highlights God’s past wonderful deeds on behalf of God’s people and that strengthen their trust in the Lord, who is able and faithful to deliver them from their present hardships.
