Although there is no requirement to subject witnesses in cases involving monetary law to the full process of questioning and interrogation, if the witnesses contradict each other with regard to the derishot or the chakirot, their testimony is nullified. If the witnesses contradict each other with regard to the bedikot, their testimony is allowed to stand. What is implied? One witness says: "He borrowed from him in Nissan," and the other witness says: "No, he borrowed in Iyar," their testimony is nullified. Or one says: "The loan was given in Jerusalem," and the second says: "No; we were in Lod," their testimony is nullified. Similarly, if one says: "He lent him a barrel of wine," and the other says: "It contained oil," their testimony is nullified, for they contradicted themselves with regard to the fundamental questions. If, by contrast, one said: "He lent him a black maneh," while the other said: "It was a white maneh. One said: "They were in the upper storey when he made the loan," and the other said: "They were in the lower storey," their testimony is allowed to stand. Moreover, even if one said: "He lent him a maneh and the other, "He lent him two hundred," the defendant is obligated to pay him at least a maneh, because 200 contains 100. Similarly, if one said: "He owes him the cost of a barrel of wine," and the other says: "...a barrel of oil," the defendant is required to pay the lesser amount of the two. Similar concepts apply in all analogous situations.
