Ohio Revised Code Title XXIX. Crimes Procedure § 2945.32

When an order has been entered by the court of common pleas in any criminal cause, directing the jurors to be kept in charge of the officers of the court, the following oath shall be administered by the clerk of the court of common pleas to said officers: “You do solemnly swear that you will, to the best of your ability, keep the persons sworn as jurors on this trial, from separating from each other; that you will not suffer any communications to be made to them, or any of them, orally or otherwise; that you will not communicate with them, or any of them, orally or otherwise, except by the order of this court, or to ask them if they have agreed on their verdict, until they shall be discharged, and that you will not, before they render their verdict communicate to any person the state of their deliberations or the verdict they have agreed upon, so help you God.” Any officer having taken such oath who willfully violates the same, or permits the same to be violated, is guilty of perjury and shall be imprisoned not less than one nor more than ten years.
