Arcana Coelestia # 3119
3119. 'And he said, Blessed be Jehovah, the God of my master Abraham' means from the Divine itself and the Divine Human. This is clear from what has been stated above in 3061, where the same words occur with the exception of 'Blessed'. 'Blessed be Jehovah' was an expression of thanksgiving, and thus also of joy and gladness, that things had turned out as one wished. In addition, as to what the ancients meant by blessing Jehovah, see 1096, 1422.
Evening
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)
