So David dances because he can’t help it. His dance is his way of saying that though he, the king, is the agent of this final chapter in a long history, this moment is not about him – it is about God and his dance is the embodiment of that truth. Dance is always about embodying something.
David conquers Jerusalem, not with a sword, but with his dance. It’s a stunning and wonderful thing. The people watching him dance, gush, and not with their blood, which, of course, is the best part about this.
