2 Samuel 3 is the third chapter of the Second Book of Samuel in the Old Testament of the Christian Bible or the second part of Books of Samuel in the Hebrew Bible. According to Jewish tradition the book was attributed to the prophet Samuel, with additions by the prophets Gad and Nathan, but modern scholars view it as a composition of a number of independent texts of various ages from c. 630–540 BCE. This chapter contains the account of David's reign in Hebron. This is within a section comprising 1 Samuel 16 to 2 Samuel 5 which records the rise of David as the king of Israel, and a section comprising 2 Samuel 2–8 which deals with the period when David set up his kingdom.
