Wisdom of Solomon
This book is probably the last book of the Old Testament and was written around 100 B.C. by an Alexandrian Jew, although he probably used earlier materials even those possibly written by King Solomon. Here the concept of wisdom is personified (and this will ultimately lead to the New Testament idea of the Word of God, that is, Christ).
The book can be conveniently divided into three parts: 1) Chapters 1-5 deal with the vital importance of Wisdom in determining the eternal destiny of men; Chapters 6-9 speak of the origin, nature and activities of Wisdom, as well as the means to acquire it; and Chapters 10-19 are a description of Divine Wisdom directing the destiny of Israel from Adam to the Exodus from Egypt.
This book is used by the Orthodox for Old Testament Readings on the occasion of many Feasts of Saints.
