I am noy saying this is a fact, I do not know, but I have heard that the term (Jew down) started with this.
When God told Abraham that He would destroy Sodom and Gomorroh (SP?), Abe asked God if He found fifty righteous men in the city, would He still destroy it. God said no. Then Abe asked "40". God said no.
Finally, Abraham got God down to 10 righteous men.
Abraham, the Father of the Jews, "Jewed" God down.
