It is a positive commandment to find witnesses, to interrogate them, to ask them many questions, and examine them closely, moving from topic to topic during the questions so that they will be silenced or recant if their testimony is duplicitous. As it says, (Deuteronomy 13:16), "And you shall search, and interrogate, and ask well." Additionally, the judges must be careful while interrogating the witnesses [lest the witness learn from the judges' statements how to lie. With seven questions they examined them:] Which seven-year cycle was it? Which year? Which month? What day of the month? What day of the week? How many hours of the day? And in which place? Even if he said "Today he killed him" or "Yesterday he killed him," they still ask them which seven-year cycle, which year, which month, which day of the month, which day [of the week], and which hour [it occurred]. Among the questions, beyond the seven which apply to everyone, there are additional [questions asked]. If they are testifying about a person, saying that he worshipped strange gods, they ask them what he worshipped and what service he performed. If they are testifying that he desecrated the Sabbath, they ask him which form of [forbidden] labor he performed and in what manner did he do it. If they are testifying that he ate on the Day of Atonement, they ask him which food he ate and how much he ate. If they are testifying that he killed someone, they ask him what he used to kill the person. And similarly, all such questions are included in the interrogation.
