God replied to Phinehas at great length, setting forth why eleven tribes had suffered so heavily. The Lord had wanted to punished them for having permitted Micah and his mother Delilah to pursue their evil ways undisturbed, though they were zealous beyond measure in avenging the wrong done to the woman at Gibeah. As soon as all those had perished who were guilty of having aided and abetted Micah in his idolatrous practices, whether directly or indirectly, God was willing to help them in their conflicts with the Benjamites.
