Waters
'Waters' particularly signify the spiritual parts of a person, or the intellectual aspects of faith, and also their opposites.

'Waters … that go softly,' as in Isaiah 8:6-7, signify spiritual things, and 'waters … strong and many,' signify falsities.
'Waters,' as in Psalms 104:3, signify divine truths.
'Waters' signify truths in the natural self, and in the opposite sense, falsities.

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)
