The Holy Bible - 1 Samuel : King James Version

The Books of Samuel, 1 Samuel and 2 Samuel, form part of the narrative history of Israel in the Nevi'im or "prophets" section of the Hebrew Bible/Old Testament, called the Deuteronomistic history, a series of books (Joshua, Judges, Samuel and Kings) that constitute a theological history of the Israelites and aim to explain God's law for Israel under the guidance of the prophets. According to Jewish tradition, the book was written by Samuel, with additions by the prophets Gad and Nathan. Modern scholarly thinking is that the entire Deuteronomistic history was composed in the period c. 630–540 BC by combining a number of independent texts of various ages.
