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

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

'Swine,' as in Matthew 7:6, signify the filthy loves that are in the hells of adulterers. They also signify people who only love worldly riches, and not spiritual riches, which are the knowledges of good and truth derived from the Word. To eat the flesh of 'swine,' as in Isaiah 65:4, signifies appropriate infernal evils.
