John Wesley on Ezra 10:15

Employed - To take care that the business should be executed in the manner proposed, that the officers and delinquents of every city should come successively in convenient time and order, as these should appoint, to keep an exact account of the whole transaction, and of the names of the cities and persons whose causes were dispatched, to give notice to others to come in their turns, and to prepare the business for the hearing of the judges. These two were priests, as their helpers were Levites; that so they might inform the persons concerned, in any matter of doubt.
