This is the third collection of books in the Old Testament which provide knowledge, truth and wisdom in understanding God and our relationship with God. This collection includes the following books:
Job, Psalms, Proverbs, Ecclesiastes and Song of Solomon
Psalms and Proverbs contain many sayings of practical wisdom to help live a free, happy, successful and holy life. Job and Ecclesiastes deal with the weightier issues of the meaning of life, the existence of evil, our relationship to God and his sovereignty. Song of Solomon is a love song glorifying romantic love between a man and woman, although it can be interpreted allegorically as a story about the love of God for Israel or the Church.
