Arcana Coelestia # 7696
7696. 'And he said, I have sinned against Jehovah your God, and against you' means an admission that he had disobeyed the Divine and the truth. This is clear from the meaning of 'sinning' as acting contrary to Divine order, dealt with in 5076, and turning away and separating oneself from it, thus from goodness and truth, 5229, 5474, 5841, 7589. As an extension of this, 'sinning' also means disobeying the Divine and the truth, for one who disobeys turns himself away. The Divine is what 'Jehovah your God' is used to mean, and the truth what Moses and Aaron are used to mean, 7695.
Arcana Coelestia # 7589
7589. 'I have sinned this time' means a separation from truth and good. This is clear from the meaning of 'sinning' as a cutting off and turning away from what is Divine, thus from truth and good, dealt with in 5229, 5474, 5841, consequently a separation also; for anyone who turns away from truth and good separates himself from them.
