Judges 19-21

The story of the Levite and his concubine reveals how quickly sin perverts and how easily sin justifies itself in the minds of men. The story begins and ends with a summary explanation that is also an excuse: there was no king in Israel. With no single person to persistently enforce God's law there were many people who chose to ignore God's law. There were men in Gibeah who sought only their own passions like the men of ancient Sodom. In the end God convicted his people to carry out his judgment on those wicked men along with the people who protected them.
