There was no king in Israel - The word מלך melech, which generally means king, is sometimes taken for a supreme governor, judge, magistrate, or ruler of any kind; (see Genesis 36:31, and Deuteronomy 33:5;); and it is likely it should be so understood here.
Every man did that which was right in his own eyes - He was his own governor, and what he did he said was right; and, by his cunning and strength, defended his conduct. When a man's own will, passions, and caprice, are to be made the rule of law, society is in a most perilous and ruinous state. Civil government is of God; and without it the earth must soon be desolated. There was a time when there was no king in England; and that was, in general, a time of scandal to religion, and oppression to men.
In those days - This phrase, indicating distinctly that the writer lived after the establishment of the kingly government in Israel, is unique to the author of these last five chapters.
