Hosea 7:7

They are all hot as an oven,

And devour their judges,

All their kings are fallen,

There is none among them who calls to me.

So the people, hot like a stoked oven, stoked by the leaders of the conspiracy, devour their judges and destroy their kings. Both princes and kings fall together to be replaced by a new regime, who will later follow the same path. Such is the perfidy of a people who have forsaken YHWH. For not one of them calls on YHWH. The true Yahwists would not be involved.

And that is the point. Having rejected YHWH Who had always been their Deliverer in the past, they have had no one to turn to. So in desperation they have tried one king after another, only to discover that each one failed in his turn, quickly to be replaced by another. It is the picture of a nation that has lost its way. And yet still they refuse to turn back to YHWH. It was a picture of obstinacy gone mad, and is typical of those who, having rejected God, spend all their lives looking desperately for another solution when there is none.
