psalmos denotes writings cited as the Psalms and compositions used in congregational singing and instruction.

The term most often identifies the Psalms as a written collection or source of quotation: verses refer to the “Book of Psalms,” the “second Psalm,” and the Psalms alongside the Law and Prophets. It also occurs for compositions used when believers address, teach, and admonish one another in singing, and for a composition brought by an individual at an assembly.

   In Acts 1:20 and Luke 20:42, the genitive plural occurs in clauses introducing words written or spoken from the “Book of Psalms.” Acts 13:33 refers to what is written in the “second Psalm,” while Luke 24:44 places the dative plural alongside the Law of Moses and the Prophets as writings that must be fulfilled.

2. Compositions used in gathered singing · common

   The dative plural appears with hymns and spiritual songs in Colossians 3:16 and Ephesians 5:19; the surrounding clauses concern teaching, admonishing, addressing one another, singing, and making melody. In 1 Corinthians 14:26, the accusative singular is one item that an individual has when the assembly gathers, alongside teaching, revelation, a tongue, and interpretation.

In the Anselm Project Bible: The APB presents the term as “Psalm” or “Psalms” when a written source or collection is in view, and as “psalms” alongside hymns and spiritual songs in the singing passages. These renderings confirm the clauses' presentation rather than isolate every contribution of the Greek form.
