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 17
17:3 Thou hast proved mine heart; thou hast visited me in the night; thou hast tried me, and shalt find nothing; I am purposed that my mouth shall not transgress.
