The writer explained editorially that there was no king in Israel at this time and everyone did as he pleased (Judges 17:6). That is the reason Micah could get away with such flagrantly disobedient behavior. Even though there was not yet a human king, Yahweh reigned as Israel’s monarch from heaven. Since His people paid no attention to His authority by disregarding His Law, Israel was practically without a king. Kings enforce standards, but in Israel the people were setting their own standards.
