Psalms
Chapter
Psalms is a collection of poems written over a long period of time by various authors. They express the heart of humanity in all generations through a variety of religious experiences. Originally the poems were chanted or sung to the accompaniment of a stringed instrument. One of the characteristics of this Hebrew poetry is parallelism; that is, the second line reiterates the idea of the first line.
Psalm 21
21:1 To the chief Musician, A Psalm of David. The king shall joy in thy strength, O LORD; and in thy salvation how greatly shall he rejoice!
