Evening, a time when the light and heat are fading away, represents a state in which a person -- or a community of people -- is turning away from the Lord, with little desire left to be good and little knowledge left regarding what good is. Evening is often a time of judgment.

In Genesis 19:1, the evening signifies the visitation that comes before judgment. (Arcana Coelestia 2318)

In Genesis 30:16, this signifies the good or truth in a state of good, but in the obscurity that is characteristic of the natural. (Arcana Coelestia 3949)

303. When the Lord was in the world his human nature was divine truth. When he was in the world, the Lord made his human nature divine truth from the divine goodness that was in him: 2803, 3194, 3195, 3210, 6716, 6864, 7014, 7499, 8127, 8724, 9199. The Lord then arranged everything within himself into the form of heaven in accord with divine truth: 1928, 3633. As a result, heaven was then in the Lord and the Lord was like heaven: 911, 1900, 1928, 3624-3631, 3634, 3884, 4041, 4279, 4523, 4524, 4525, 6013, 6057, 6690, 9279, 9632, 9931, 10303. The Lord spoke from the divine truth itself: 8127. So in the Word, the Lord used correspondences when he spoke: 3131, 3472-3485, 8615, 10687. As a result, the Lord is the Word and is called the Word, which is divine truth: 2533, 2813, 2859, 2894, 3393, 3712. In the Word, "the Son of Humanity" means divine truth and "the Father" means divine goodness: 2803, 3704, 7499, 8724, 9194. Since the Lord was divine truth, he was also divine wisdom: 2500, 3382. Only the Lord's perception and thinking came entirely from himself, and they transcended all angelic perception and thinking: 1904, 1914, 1919. His divine truth was susceptible to spiritual assault; his divine goodness was not: 2824.
