Judges 8:23

I will not rule over you As a king. He rejected their offer, because he looked upon God as their king, who appointed what deputy he pleased to govern them; and because he considered this proposal as an effort, or at least as tending to alter that form of government which God had instituted and had given them no authority to change. The Lord shall rule over you In a special manner, as he hath hitherto done by judges. These God particularly appointed and directed in all the more important concerns of their office, even by Urim and Thummim, and, in a special manner, assisted upon all occasions: whereas kings had only a general dependance on God. That God was their supreme Ruler and King, was the foundation of their whole state. Hence the judgment which was administered among them is called God's judgment, Deuteronomy 1:17. And Solomon is said to sit upon the throne of the Lord, (1 Chronicles 29:23,) and the kingdom of his posterity is called the kingdom of the Lord, (2 Chronicles 13:8,) because before kings were settled in Israel, the Lord was their king; from whom the government was derived to the house of David by a special act of God.
