When did the book of ruth have being published.

The Book of Ruth is a part of the Hebrew Bible, and it is traditionally believed to have been written during the time of the monarchy in Israel, possibly during the reign of King David. However, it was likely composed in its final form around the 5th or 4th century BCE. It is important to note that the Book of Ruth was not published in the modern sense; rather, it was passed down through oral tradition and later written down as part of the biblical text. The Book of Ruth is included in the Christian Old Testament as well and has been part of the biblical canon for centuries.
