The entire collection of Psalms is entitled “Praises” in the Hebrew text. Later, rabbis often designated it “The Book of Praises.” The Septuagint (LXX)1, the Greek translation of the OT, labeled it “Psalms” (cf. “The book of Psalms” in the NT: Luke 20:42; Acts 1:20). The Greek verb from which the noun “psalms” comes basically denotes the “plucking or twanging of strings,” so that an association with musical accompaniment is implied. The English title derives from the Greek term and its background. The Psalms constituted Israel’s ancient, God-breathed (2 Tim. 3:16) “hymnbook,” which defined the proper spirit and content of worship.
