Miss. Code Ann. § 13-5-89

In all cases where a jury is required in the exercise of the right of eminent domain, the sheriff and clerks of the circuit and chancery courts shall draw eighteen names from the jury box, and the slips containing the names shall be returned to the box. The sheriff shall summon the jury thus drawn, and the jurors shall attend, under the same penalties as in the circuit court, and the penalties may be enforced therein at the next term, on complaint of the proper party or of the sheriff.
