9. One who had forbidden relations (punishable by Kores) and fathers a mamzer (illegitimate child) - the disgrace will never leave, and the wrong cannot be corrected, as written: "For that is lewdness, and it is iniquity to be punished by the judges; For it is fire; it consumes to destruction" (Iyov 31:11), and "They betrayed the L-ord for they begot strange children" (Hoshea 5:7).
