While looking up something else, I came upon Leviticus 19:33:
When a foreigner resides among you in your land, do not mistreat them. The foreigner residing among you must be treated as your native-born. Love them as yourself, for you were foreigners in Egypt.
I wonder what the religious right would be like if they actually read their Bibles. Then again, they’d keep going to Deuteronomy 20:13, so I should probably be glad on the whole:
When you march up to attack a city, make its people an offer of peace. If they accept and open their gates, all the people in it shall be subject to forced labor and shall work for you. If they refuse to make peace and they engage you in battle, lay siege to that city. When the Lord your God delivers it into your hand, put to the sword all the men in it. As for the women, the children, the livestock and everything else in the city, you may take these as plunder for yourselves.
