Songs
In the ancient and Jewish churches, 'songs' were prophesies about the Lord, especially His coming in the world, subjugation of evil spirits, and liberation of the faithful from their assaults. 'Heavenly songs' are voiced affections or affections expressed and modified by sounds. As thoughts are expressed by conversation, so affections are expressed by songs. From the balance and flow of the variations, angels perceive the object of the affection.

Arcana Coelestia # 2858
2858. 'And went together to Beersheba' means advancement in the doctrine of charity and faith, which doctrine is Divine and to which human rational ideas were allied. This is clear from the meaning of 'Beersheba' as the doctrine of charity and faith, which is Divine and to which human rational ideas were allied, dealt with in 2614, 2723. Human rational ideas are meant by 'the servants', 2782, 2792, 2856; and that the doctrine to which they were allied was Divine is meant by the statement about them going together with Abraham, see 2767.
