Canon 10 & 26 issued by Council of Szaboles [Hungary]: “[Canon 10] If Jews should associate to themselves wives of Christians or keep in their service and Christian, such a person shall be taken from them and restored to freedom, while the price money shall be taken from his sellers and transferred to the maintenance expenses of the bishops…[Canon 26] If anyone should discover a Jew working on Sunday or on other high holidays, he shall lose the tools he will be using, lest Christianity be scandalized.”
