Arcana Coelestia #4090
4090. 'Where you anointed a pillar' means where the good of truth exists, and the boundary of it. This is clear from the meaning of 'a pillar' as a holy boundary and so the ultimate degree of order, and therefore as truth, dealt with in 3727, and from the meaning of 'anointing', or pouring oil, as Jacob did, over the head of the pillar, as making truth good, dealt with in 3728.
Arcana Coelestia #3729
3729. 'And he called the name of [that] place Bethel' means the nature of the state. This is clear from the meaning of 'name' and 'calling the name' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006, 3421, and from the meaning of 'place' as state, dealt with in 2625, 2837, 3356, 3387. The nature of the state is what 'Bethel' means. In the original language Bethel means God's house, which is good as it exists in the ultimate degree of order, see 3720.
