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.
Four
The number "four" in the Bible represents things being linked together or joined. This is partly because four is two times two, and two represents the ultimate linking between our desire to be good and our understanding of truth. We can also see this in the fact that most buildings are rectangular, with the four sides linking together to make a whole. We also divide directions into four -- north, east, south and west -- and talk about the "four corners" of something meaning all of it. So our special thinking naturally looks at four sides as linking together into a whole.
