Womb and belly
In Psalm 58:3, a womb signifies that good is to appear, and the belly, that truth is. (Apocalypse Explained 710[5])
Arcana Coelestia # 10671
10671. 'And the feast of ingathering at the end of the year' means the worship of a thankful mind on account of the implanting of good after that, and so on account of regeneration and complete deliverance from damnation. This is clear from what has been shown regarding this feast in 9296.
