This is the joke;
2 The kings of the earth set themselves, and the rulers take counsel together, against the Lord, and against his anointed, saying,
3 Let us break their bands asunder, and cast away their cords from us
So here we have the rulers of nations trying to put God out of the picture. Well that's just impossible. They're forgetting who's Earth it is in the first place. You might as well live in a room of the King's palace, command your servants and suggest to other guests that you throw the King out.
