There are tons of excellent freely/easily available journal articles out there. Here are some I’ve found useful, divided up into themes.
That the god of the Hebrew Bible appears to be a homicidal maniac has not escaped the notice of anti-theists and thoughtful theists. It is considered to be one of Christianity’s greatest apologetic difficulties, and, by their flat reading of the text has caused some Christian apologists to become, in effect, apologists for genocide.
These papers provide some context around the topic and demonstrate that a historical-critical reading of the text, while not doing away with the problem altogether, shows us that what appears to be Divinely-Sanctioned violence may not be that at all.
Josiah in the book of Joshua
Richard D. Nelson, Journal of Biblical Literature, Vol. 100, No. 4 (Dec., 1981), pp. 531-540.
The Joshua of Deuteronomy is in many ways a thinly disguised Josianic figure who acts out the events of the Deuteronomist’s own day on the stage of the classical past. Against the backdrop of Gilgal, Ai, and Hazor, he struts out a deuteronomistic script recalling contemporary events involving Jerusalem, Bethel, and a Judean expansion to the north. While all this was obvious to the Deuteronomist’s seventh-century readers, the passage of years and later exilic redaction have made Joshua’s make-up and costume less transparent than originally intended. In this study we have tried to capture afresh what the Deuteronomist was trying to do in the book of Joshua.Richard D. Nelson, Journal of Biblical Literature, Vol. 100, No. 4 (Dec., 1981), 540.
