Stranger
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.
Deuteronomy 24:14-15
14
You shall not oppress a hired servant who is poor and needy, whether he be of your brothers, or of your foreigners who are in your land within your gates:
15
in his day you shall give him his hire, neither shall the sun go down on it; for he is poor, and sets his heart on it: lest he cry against you to Yahweh, and it be sin to you.
