Dating the texts of the Hebrew Bible is a controversial endeavor, but most Biblical scholars agree at least that all of the books of the Hebrew Bible (except Daniel) were complete and more or less in their present form by the third century B.C.E. Some of us argue for an earlier date for the majority of the books in their final form by two or more centuries, and there are good arguments based on language, content and archaeology for some Biblical texts as early as the tenth century B.C.E. (see, e.g., William Dever, What Did the Biblical Writers Know and When Did They Know It? [Grand Rapids, MI: Eerdmans, 2002], especially chapter 4).
