How does the Bible say the government should treat foreigners?


“Everyone who is native-born must do these things in this way when they present a food offering as an aroma pleasing to the Lord. For the generations to come, whenever a foreigner or anyone else living among you presents a food offering as an aroma pleasing to the Lord, they must do exactly as you do. The community is to have the same rules for you and for the foreigner residing among you; this is a lasting ordinance for the generations to come. You and the foreigner shall be the same before the Lord:  The same laws and regulations will apply both to you and to the foreigner residing among you.” Numbers 15:13-16
            The community of Israelites traveling in the wilderness included outsiders they picked up along the way, and some Egyptians.  God had a clear way to handling them—they must follow the same rules as everyone else.  They were not treated special with any extra benefits, but the same expectations for the nationals applied to the foreigners.
