Samuel and Kings (as well as Chronicles) were first divided into two books in the Greek translation of the Bible known as the Septuagint. The Septuagint dates to the third century B.C., and was made in Egypt where it was copied on papyrus scrolls. At that time, papyrus scrolls could not be practically made as long as parchment or leather scrolls that were used in Judea. Hence, in the Septuagint, Samuel and Kings (as well as Chronicles) were each divided into two parts, designated first and second.
