Who Is Fit to Judge and Who Is Not

And he shall not be biased towards him, in order to disqualify those who hate him from sitting in judgment. I only have a source for disqualifying haters; how do I know to include relatives? Therefore, it is stated: "Between the one who strikes and the avenger of blood." I only have a source for judges who disqualify haters and relatives; how do I know about witnesses? Therefore, since you are judging, and the Torah said, "put to death based on the testimony of witnesses," just as judges disqualify haters and relatives, witnesses also disqualify haters and relatives. Furthermore, what applies to judges, who have ongoing authority, to disqualify haters and relatives, does not apply to witnesses, as their authority is not ongoing, and they do not disqualify haters and relatives. I only have a source for the case of a murderer; how do I know about other capital offenses? Therefore, it is stated: "These judgments." I only have a source for the people of Israel; how do I know about converts? Therefore, it is stated: "These judgments shall be for you as for the native-born." I only have a source for cases involving loss of life; how do I know about cases involving monetary matters? Therefore, it is necessary to state: "Upon these judgments." Just as cases involving loss of life are included in these judgments, so too cases involving monetary matters are included in these judgments. But how do I know that cases involving monetary matters are not included in these judgments? Therefore, it is stated: "These judgments." How do I know about cases involving loss of life? It is stated: "And the congregation shall judge, resulting in ten." And it is stated: "And they shall save the congregation, resulting in ten." And how do I know about three additional judges? Since the Torah said, "put to death based on the testimony of witnesses," just as witnesses are two, judges are also two, and a court cannot add another one, thus we have three judges. Some interpreters of the Scriptures say that three testimonies are mentioned in the passage to teach you that cases involving loss of life require three judges.
