Phyllis Trible in Texts of Terror: Literary-Feminist Readings of Biblical Narratives (Philadelphia: Fortress, 1994), p. 79, speculates that the concubine may have still been alive at the time of her dismemberment. In this, she echoes Robert Polzin, Moses and the Deuteronomist (New York: Seabury Press, 1980). This is possible, but not relevant to my point. But see Judges 20:5.
