The execution must intelligibly refer to the judgment, stating the time when and place at which it was rendered, the names of the parties to the action as well as to the judgment, its amount, and the amount still to be collected thereon, if for money; if not, it must state what specific act is required to be performed. If it is against the property of the judgment debtor, it shall require the sheriff to satisfy the judgment and interest out of property of the debtor subject to execution.
