In Revelation 18:13, 'wine, oil, flour, and wheat' signify celestial principles of worship.

(Referencat: Apocalypse Revealed 777)

'Sons of the stranger' signify counterfeit truths, or falsities. 'Our sons' signify the doctrines of truth, and 'our daughters,' the doctrines of good, as in Psalm 144:11-12.
