C. F. Keil and Franz Delitzsch on Joshua 10:20-21

Jos 10:20-21

When the great battle and the pursuit of the enemy were ended, and such as remained had reached their fortified towns, the people returned to the camp to Joshua at Makkedah in peace, i.e., without being attacked by anybody. “There pointed not (a dog)its tongue against the sons of Israel, against any one” (see at Exo 11:7). לאישׁ is in apposition to ישׂראל לבני, and serves to define it more precisely. It is possible, however, to regard the ל as a copyist’s error, as Houbigant and Maurer do, in which case אישׁ would be the nominative to the verb.
