The Mishnah taught that if perjurers testified that a man divorced his wife and had not paid her ketubah, seeing that her ketubah would ultimately have to be paid sooner or later, the assessment was made based on the value of the woman's ketubah in the event of her being widowed or divorced or, alternatively, her husband inheriting her after her death. If perjurers testified that a debtor owed a creditor 1,000 zuz due within 30 days, while the debtor says that the debt was due in 10 years, the assessment of the fine is made on the basis of how much one might be willing to offer for the difference between holding the sum of 1,000 zuz to be repaid in 30 days or in 10 years.
