How many books are there in the book of Psalms?

The book of Psalms is divided into five distinct sections, often referred to as "books." This structure is observed in both the Hebrew Bible and the Christian Old Testament. Each of these sections contains a varying number of individual psalms, reflecting different themes and literary styles. This division into five books serves to organize the psalms and highlights the richness of the text, facilitating both individual and communal worship practices. Each book concludes with a doxology, further reinforcing this structure. Understanding that the Psalms are grouped into five books helps to appreciate the theological and literary design of this central text in both Jewish and Christian traditions.
