'Being sent' means coming forth, (or going forth), in the internal sense, as in John 17:8. In similar manner, it is said of the holy of the spirit, that it was 'sent,' that is, it goes forth from the divine of the Lord, as in John 15:26, 16:5, 7.

So, too, the prophets were called 'the sent,' because the words which they spoke went forth from the holy of the spirit of the Lord.

'To be sent,' as in Genesis 37:13, signifies teaching.

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.
