No king, i.e. no judge to govern and control them. The word king being here used largely for a supreme magistrate; as Genesis 36:31 Deuteronomy 33:5. God raised up judges to rule and deliver the people when he saw fit; and at other times for their sins he suffered them to be without them, and such a time this was; and therefore they ran into that idolatry from which the judges usually kept them, as appears by that solemn and oft-repeated passage in this book, that after the death of such or such a judge the people forsook the Lord, and turned to idols. That which was right in his own eyes, i.e. not what pleased God, but what best suited his own fancy or lusts.
