What categories of items are excluded from oaths of the judges? How is this derived from the Torah? What is the argument between Rabbi Meir and the rabbis in the mishna regarding items that are or are not considered like land (to exempt from oaths)? Another criterion for oaths is that it must be regarding an item that is measurable – the gemara explains the cases described in the mishna relating to this and Rava and abaye debate a particular case. If one loans money with collateral and the item gets lost, what type of responsibility does the creditor assume for the item? What if the creditor and debtor disagree regarding the value of the lost item? Shmuel holds that the creditor no longer owes any money even if the item is worth significantly less than the loan. How does his opinion work with the mishna?
