In Griffith's electrodynamics he writes about poynting's theorem.He considers some charge and current configuration. Then he says that these charges move.Which charges is he talking about and why would they move?

What's your objection to moving charges? Currents are produced by moving charges. In general, a given charge can also accelerate due to the forces experienced by the electric and magnetic field produced by the other charges.

Which charges is he talking about and why would they move?
Any charges moving for any reason. It is a general proof.

Ok the current density J which comes in proceeding steps is due to motion of these charges but when he uses ampere Maxwell law he relates it to same E and B which are due to some other source.
