For an ingenious, unbelieving account of how "editors," "redactors" and "compilers" have confused this battle with Jabin's army under Sisera vs. the forces led by Barak, with the account in  Joshua 11 of another battle with the Canaanites more than a century before the battle reported here, one should read Soggin's Commentary on Judges.  Careless commentators are totally in error in such unwarranted conclusions!
