The Book of Psalms is Israel's hymnbook and prayerbook, a collection of 150 poems that together span the full emotional and theological range of biblical faith. Composed across centuries and gathered from multiple sources, the Psalms include hymns of praise, communal and individual laments, royal psalms, wisdom poems, songs of thanksgiving, and liturgies tied to temple worship and pilgrimage. They give voice to joy, grief, fear, anger, confidence, and longing, addressing God in language that has shaped Jewish and Christian devotion for over two millennia.
The Hebrew title Tehillim ("Praises") highlights the book's doxological climax, while many individual psalms are tephillot ("prayers"). The Greek title Psalmoi reflects their musical setting on stringed instruments. The collection moves from the orderly Torah-centered piety of Psalm 1 through cycles of crisis, confession, and exuberant praise to the cascading hallelujahs of the final psalms.
More than any other biblical book, Psalms speaks in the second person to God rather than in the divine voice to humans. It has functioned as Israel's response to revelation, the daily prayer of synagogue and monastery, and the lyrical foundation of countless hymns and spiritual songs. Its poetry teaches readers not only what to believe about God but how to address him in every condition of life.
