What is the difference between the chakirot and the derishot and the bedikot? With regard to the chakirot and the derishot, if one witness gave specific testimony and the second said: "I do not know," their testimony is of no consequence. With regard to the bedikot, by contrast, even if both of them say: "I don't know," their testimony is allowed to stand. If, however, they contradict each other, even with regard to the bedikot, their testimony is nullified. What is implied? The witnesses testified that one person killed another. One of the witnesses specified the year of the seven year cycle, the year, the month, the date, the day of the week, Wednesday, the time, 12 noon, and the place of the murder. Similarly, they asked him: "With what did he kill him?", and he answered: "With a sword." If the second witnesses outlined his testimony in the same manner except for the time, i.e., he said: "I do not know the time of day at which the murder took place," or he was able to specify the time, but said: "I don't know what he used to kill him. I did not take notice of the murder weapon," their testimony is nullified. If, however, they outlined all the above factors identically, but were asked: "Was he dressed in black or white?" their testimony is allowed to stand if they replied: "We don't know. We did not pay attention to factors like these which are of no consequence."
