"Now this was the sin of your sister Sodom: She and her daughters were arrogant, overfed and unconcerned; they did not help the poor and needy." That would Ezekiel 16:49.
I wouldn't bother mentioning this -- what with me being an atheist, and all -- except that, in my life, the people I hear protesting the most loudly against taking in refugees or living in the same country as Muslims are the same ones who speak the most loudly about their Christian faiths. Also:
"When a stranger resides with you in your land, you shall not do him wrong. The stranger who resides with you shall be to you as the native among you, and you shall love him as yourself, for you were aliens in the land of Egypt; I am the LORD your God." That one would be Leviticus 19:33-34.
As Ezekiel (a notoriously cranky old bastard) might have said: Listen and take heed, motherfuckers.
