Adam Clarke on Judges 8:22

Rule thou over us, both thou, and thy son, and thy son's son - That is, Become our king, and let the crown be hereditary in thy family. What a weak, foolish, and inconstant people were these! As yet their government was a theocracy; and now, dazzled with the success of a man who was only an instrument in the hands of God to deliver them from their enemies, they wish to throw off the Divine yoke, and shackle themselves with an unlimited hereditary monarchy! An unlimited monarchy is a curse; a limited monarchy may be a blessing: the latter may be an appointment of God; the former never can. Those who cast off their allegiance to their Maker, are guilty of folly and extravagance of every kind.
