Definition:

The term "foreigner" refers to a person living in a country that is not his own. Another name for a foreigner is an "alien."

In the Old Testament, this term especially refers to anyone who came from a different people group than the people he was living among.
A foreigner is also a person whose language and culture is different from those of a particular region.
For example, when Naomi and her family moved to Moab, they were foreigners there. When Naomi and her daughter-in-law Ruth later moved to Israel, Ruth was called a "foreigner" there because she was not originally from Israel.
The apostle Paul told the Ephesians that before they knew Christ, they were "foreigners" to God's covenant.
Sometimes "foreigner" is translated as "stranger," but it should not refer only to someone who is unfamiliar or unknown.
A "sojourner" is a person who is living in one country that is not his but waiting for the chance to move to his own country.
A "barbarian" is a person from another country who does not speak the local language or obey the local customs and so the natives do not like or respect him.
To be "alienated" is to no longer be living in loving relationship with another. For example, aß husband and wife who are no longer living together but are not divorced are "alienated" or "estranged."
