Some ancient authorities, rabbins and others attribute the book to Solomon; others hold that it has a composite origin and is the work of a number of writers. The ablest modern critics hold the latter opinion. It is probable that Solomon was the author of the portion beginning with the first verse of the tenth chapter and ending with the sixteenth verse of the twenty-second chapter. As we learn from the first verse of the twenty-fifth chapter, the collection of proverbs extending to the end of the twenty-ninth chapter was also attributed to him, but was not compiled until 250 years after his death. The remainder of the book appears to be composed of six portions by different hands at different periods. One of these is the introduction, which occupies the first nine chapters. This was probably written by the man who compiled the whole book, but whose name is unknown.
Who Composed the Psalms? The Book of Psalms (which is the Psalter of the Hebrews) has many authors, the principal one being David. Some are attributed to Hezekiah, Josiah, and Zerubbabel, two (the 72nd and 127th) to Solomon, several to the Levites and the Asaphites, one, at least, to Jeduthun, eleven to the sons of Korah, one to Ethan (Psalm 89), while many are of uncertain authorship. Moses is given by tradition as the author of Psalm 90, being the only contribution of which his authorship is reasonably certain. The Psalms cover a period of a thousand years. They were composed at different remote periods, by various poets; David, the most prolific contributor, being' indicated as the author of seventy-three Psalms in the Hebrew text and eleven in the Septuagint
