Arcana Coelestia #1314
1314. Verse 6 And Jehovah said, See, they are one people, and they all have one lip, and this they have started to do; and now they will not be held back from anything which they have thought of doing.
'Jehovah said' means that it was so. 'See, they are one people, and they all have one lip' means that all had the truth of faith and held to the same doctrine. 'And this they have started to do' means that they are now starting to become different. 'And now they will not be held back from anything which they have thought of doing' means unless their state is now altered.
