레위기 20:4의 미드라쉬

7) This tells me only of kosher seed. Whence do I derive (the same) for seed that is pasul (such as a mamzer)? From (Vayikra 20:4) "when he gives of his seed to the Molech" — all seed.

9) (Vayikra 20:4) ("And if the people of the land avert, they shall avert their eyes from that man when he gives of his seed to the Molech, not to kill him.") Whence is it derived that if they "avert" in one thing, they shall "avert" in many things? From "And if avert, they shall avert."

10) And whence is it derived that if one beth-din averts (its eyes), many batei-din are destined to do so? From "And if avert, they shall avert."
