this jewish belief comes from the 'rabbi and the ladder' story you may have heard before.
and if you scroll up from that part of the talmud it basically reads:
>No! Lies will bring us closer to our father satan than money! Therefore the jew should lie and let the goy die than save him for shekels!

as you can see i used nothing but jewish primary religious sources (the talmud) to come to this conclusion.
