As far as we know, King Solomon never wrote anything, biblical or otherwise. The First Book of Kings, written centuries after the time of Solomon, gives us the defining legend of Solomon, his great wisdom, gifted to him by God. Jewish tradition has built up an image of Solomon as a great and wise ruler, and the Song of Songs has been attributed to him, as have the wisdom books of Proverbs and Ecclesiastes. However, scholars say that these books were all written long after the time of Solomon and show no evidence of his legacy.
How reliable is the Hebrew tradition?
"Although critics contended that the Hebrew Bible is untrustworthy, time and time again, the archaeological record supports places, times, and events mentioned in Scripture." (Professor John Arthur Thompson, The Bible and Archaeology). The personal names Abraham, Isaac, and Jacob are names of the time and area mentioned in the Bible (ibid).
"One city after another, one civilization after another, one culture after another, who were known only from the Bible, have been restored to their place in ancient history through archaeology" (Prof. Gleason Archer, A Survey of Old Testament Introduction).
No parchment, scroll, or inscription has ever been found that would support the Bible-critics' JEPD (different sources) hypothesis, which remains a set of mere postulates. And those ancient writers who mention, describe, summarize or translate the Torah (Josephus, Samaritans, Targum, Septuagint etc.), describe it in its complete form.
Archaeological finds, such as the Ugarit documents and those of Nuzu, Mari, Susa, Ebla, and Tel el-Amarna, have repeatedly caused the critics to retract their claims. The entire social milieu portrayed in the Torah, once criticized as anachronistic, has been shown to be accurate, including customs of marriage, adoption, contracts, inheritance, purchases, utensils, modes of travel, people's names and titles, etc. Professor Gleason Archer states: "In case after case where inaccuracy was alleged as proof of late and spurious authorship of the biblical documents, the Hebrew record has been vindicated by the results of excavations, and the condemnatory judgment of the Documentary theorists have been proved to be without foundation."
