'The children of Israel,' in Isaiah 14:2, signify the Gentiles.

In Jeremiah 23:8, 'Israel' represents the spiritual natural church.

(参考: Apocalypse Explained 768)

Egyptians represent people who are in natural knowledge. In contrast, the Hebrews, people who are of the church, represent people in spiritual knowledge. The Egyptians also held the Hebrews to be so vile, as servants, that it was an abomination to them to eat with the Hebrews (Genesis 43:32), and also the sacrifices offered by the Hebrews were an abomination to them. (Exodus 8:26)
