The book of Proverbs belongs to a group of works in the Hebrew literature the subject of which is Wisdom. It is probably the earliest of them all, and may be regarded as the stem, of which they are the branches. Without attempting to determine the relative ages of these compositions, the ordinary reader can see the points of contact between Proverbs and Ecclesiastes, and a little careful study reveals that the book of Job, though fuller and richer in every respect, belongs to the same order. Outside the canon of Holy Scripture we possess two works which avowedly owe their suggestion and inspiration to our book, viz. "The Wisdom of Jesus the Son of Sirach," commonly called Ecclesiasticus, a genuinely Hebrew product, and "The Wisdom of Solomon," commonly called the Book of Wisdom, of much later origin, and exhibiting that fusion of Hebrew religious conceptions with Greek speculation which prevailed in the Jewish schools of Alexandria. Now, the question at once occurs, What are we to understand by the Wisdom which gives a subject and a title to this extensive field of literature? and in what relation does it stand to the Law and the Prophets, which form the great bulk of the Old Testament Scriptures? Broadly speaking, the Wisdom of the Hebrews covers the whole domain of what we should call Science and Philosophy. It is the consistent effort of the human mind to know, to understand, and to explain all that exists. It is, to use the modern phrase, the search for truth. The "wise men" were not, like Moses and the Prophets, inspired legislators and heralds of God's immediate messages to mankind; but rather, like the wise men among the earlier Greeks, Thales, Solon, Anaximenes, or like the Sophists among the later Greeks, Socrates and his successors, they brought all their faculties to bear in observing the facts of the world and of life, and in seeking to interpret them, and then in the public streets or in appointed schools endeavoured to communicate their knowledge to the young. Nothing was too high for their inquiry: "_That which is_ is far off, and exceeding deep; who can find it out?"[2] yet they tried to discover and to explain _that which is_. Nothing was too lowly for their attention; wisdom "reaches from one end to another mightily, and sweetly orders all things."[3] Their purpose finds expression in the words of Ecclesiastes, "I turned about, and my heart was set to know and to search out, and to seek wisdom and the reason of things."[4]
