No need for that.Jews had nothing against slavery,but christianity from the start teached that slaves are as good children of God as their masters.
They only never supported any kind of revolution.
They conqered Roman Empire in half of year,and made factories for rest of the time.When supplie end,they would be with 1900 level technology.Still perfectly capable of conqering rest of the world.
If they do not get factories with workers,too - Rome would become superpower after taking their technology.Rifle without ammo is poor mace.
And our world would be f****d.
