We especially decree, by the following law, that it shall not be lawful for any Jew to testify against a Christian in any legal proceeding, or business transaction, even though said Christian should be of the lowest rank or a slave; nor shall a Jew prosecute a Christian, in any action at law; or sue him upon any written contract; or subject him to torture for any reason whatever. For it seems sacrilegious to prefer an infidel to him who is a believer, and to subject the members of the followers of Christ to torture inflicted by his adversaries. If, however, Jews should have causes of action among themselves, they shall have the right, under the law, to testify against each other; and to put their slaves to the torture in the presence of Christian judges. =X. No Jew shall Testify Against a Christian; and Under what Circumstances the Descendants of Jews may Testify.= If he who is convicted of having uttered a falsehood becomes infamous in the sight of all men, with how much more reason should he be excluded from giving testimony who denies the truth of the Divine Faith? Jews, whether baptized or unbaptized, are therefore forbidden to testify against Christians. The descendants of Jews, however, if they are of good morals, and adherents of the Faith, shall be permitted to give evidence among Christians; but not unless their morals and their belief shall be vouched for by either the king, a priest or a judge. =XI. No Jew shall Circumcise a Christian Slave.= It shall not be lawful for a Jew to purchase a Christian slave, or to accept of one as a gift. Should a Jew purchase such a slave or accept of him as a gift and then circumcise him, he shall lose the price of said slave, and the latter shall be free. The Jew who circumcises a Christian slave shall forfeit all his property to the king. Any slave of either sex who is unwilling to become a Jew, shall receive his or her freedom. =XII. Concerning the Penalties to be Inflicted for Offences Committed by Jews.= The following law is derived from others of great severity, which have been enacted to punish the perfidy of the Jews; and it is hereby decreed that whoever attempts to commit any of the crimes prohibited by former laws, or contained in any amendments to the same, or presumes to act in defiance of said laws, shall be either stoned to death, or burned by such of his own countrymen as may have entered into an agreement to do so. However, if the king, in his mercy, should decide to spare the life of such a criminal, he shall be delivered up as a slave to whomever the king may select, and all his property shall be given to others; and this shall be done in such a way that the culprit can never come into possession of his property again, or recover his liberty in the future. =XIII. Concerning Christian Slaves who are Known to have been Sold or Liberated by Jews.=
