The word "stranger" is used many times in the Bible, and it is sometimes paired with the word "sojourner". They are different concepts in the Hebrew, and some translations make the mistake of using them interchangeably. 'A sojourner', like 'a stranger', indicates a newcomer and inhabitant from another land; but 'a sojourner' refers to people who were taught and accepted the Church's truths, whereas those who were not taught them because they were unwilling to accept them are called 'strangers'. (Arcana Coelestia 8002)

In Ezekiel 28:7, 'strangers' signify falsities which destroy truths, and 'the terrible of the nations' signifies evils which destroy good.
