1207. Verse 19 And the border of the Canaanites was from Sidon as you come towards Gerar, as far as Gaza, as you come towards Sodom and Gomorrah, and Admah and Zeboiim, as far as Lasha.

Here, as previously, 'Sidon' means exterior cognitions. 'Gerar' means things that have been revealed concerning faith. 'Gaza' means things that have been revealed concerning charity. 'The border of the Canaanites was from Sidon as you come towards Gerar, as far as Gaza' means the extension of cognitions towards truth and good with those who have external worship devoid of internal. 'As you come towards Sodom, Gomorrah, Admah, Zeboiim, as far as Lasha' means the falsities and evils which encompass them.
