I can't take credit for something I haven't done. All that's necessary is to open The Bible and read what it says. Throughout Judges the idea that God leads Israel is paramount but it's quite evident they're aware what kings are. The Israelites often thought they knew better than God either by cooking up novel ways to obligate Him or by outright hedonism.
KING CHUSHANRISHATHAIM
Idols and revolting antics never sit well with God. The first king mentioned in Judges found The Israelites sitting ducks because they had abandoned God. Thus it's certain that they knew what a king was and could observe first hand the alternatives to accepting God. The Bible explains:
Judges 3:7-8 The children of Israel did evil in the sight of the LORD, and forgat the LORD their God, and served Baalim and the groves. Therefore the anger of the LORD was hot against Israel, and he sold them into the hand of Chushanrishathaim king of Mesopotamia: and the children of Israel served Chushanrishathaim eight years.
God also tells us about administrative affairs elsewhere. Later on there was some awkwardness concerning who'd be better placed to govern Sechem. As usual the Midianites had been marauding about the place or at least attempting to (some people never learn) but Gideon had stepped up to the mark, sorting them out in short order.
Judges 8:22-23 Then the men of Israel said unto Gideon, Rule thou over us, both thou, and thy son, and thy son's son also: for thou hast delivered us from the hand of Midian. And Gideon said unto them, I will not rule over you, neither shall my son rule over you: the LORD shall rule over you.
The Israelites just kept getting it wrong. The first time I put my hand in an electric light fitting and turned on the switch was also the last. The experience was short lived, well under a second, but these people were
ENSLAVED FOR 8 YEARS. for doing whatever worshipping idols involves which I won't try to imagine but I'm certain it's extremely impolite and what did they do next? Once they were free? Whoring it up with idols!
Judges 8:33-34 As soon as Gideon was dead, that the children of Israel turned again, and went a whoring after Baalim, and made Baalberith their god. And the children of Israel remembered not the LORD their God, who had delivered them out of the hands of all their enemies on every side.
