Fury is a receding from good, and anger is a receding from truth.

In Genesis 49:20, this signifies turning away from confirmed truth. (Arcana Coelestia 6359)

In Exodus 15:7, this signifies the fury of lusts and their endeavor to inflict violence. (Arcana Coelestia 8284)

In Zephaniah 1:15, this signifies the advent of the Lord to judgment. (Divine Love and Wisdom 5)

In Revelation 14:10, this signifies truth from which comes good. (Apocalypse Revealed 635)

9388. 'And built an altar under the mountain' means a representative sign of the Lord's Divine Human in respect of Divine Good from Him. This is clear from the meaning of 'an altar' as a representative sign of the Lord's Divine Human, dealt with in 921, 2777, 2811, 4489, and therefore the chief representative of worship of the Lord, 4541, 8935, 8940; and from the meaning of 'the mountain' as the good of love, dealt with in 4210, 6435, 8327, 8658, 8758, in this instance the Divine Good of love which emanates from the Lord, since it was Mount Sinai, where the Lord was then. 'Mount Sinai' means Divine Good united to Divine Truth emanating from the Lord, see 8805.
