Arcana Coelestia #1251
1251. Verse 31 These were the sons of Shem, according to their families, according to their tongues, in their lands, according to their nations.
'These were the sons of Shem' means derivatives of the internal worship meant by 'Shem'. 'According to their families, according to their tongues, in their lands, in their nations' means according to the disposition of each of them in particular and in general - 'according to their families' is according to differences as regards charity, 'according to their tongues' is according to differences as regards faith, 'in their lands' is in general in relation to matters of faith, 'in their nations' is in general in relation to matters of charity.
Ezekiel 44:1-2
1
Then he brought me back by the way of the outer gate of the sanctuary, which looks toward the east; and it was shut.
2
Yahweh said to me, This gate shall be shut; it shall not be opened, neither shall any man enter in by it; for Yahweh, the God of Israel, has entered in by it; therefore it shall be shut.
