The Book of Psalms called after King David, its Author, who sung them as the Talmud tells us: "A harp was suspended above the bed of David. When midnight came the north wind blew on it and it produced music of its own accord. Immediately David arose and occupied himself with Torah." For generations hence the recital of the whole Book of Psalms has become widespread, whether as an act of piety by saintly individuals, or by groups of unlearned people. For this purpose "societies of reciters of psalms" (hevrot tehillim) were formed, and in recent times a special society has been formed in Jerusalem whereby two separate groups recite the whole Book of Psalms daily at the Western Wall. The psalms are included in their entirety in all large prayer books.
