A 'void', or 'Vacuity' denotes a person's state before regeneration. From Arcana Coelestia 7: "The first state is the state which precedes, both the state existing from earliest childhood onwards and that existing immediately before regeneration; and it is called a void, emptiness, and thick darkness.

In Genesis 1:2, this signifies lacking good, as with man's state before regeneration. (Arcana Coelestia 17)

In Psalm 89:39, this signifies that the Jewish nation had destroyed its conjunction with the Lord and the church. (The Inner Meaning of the Prophets and Psalms 339)

17. Verse 2 And the earth was a void and an emptiness, and there was thick darkness over the face ¹ of the deep; and the Spirit of God was hovering over the face ¹ of the waters. The person who has yet to be regenerated is called 'a void and an empty earth', and also 'ground', in which no good or truth at all has been sown - 'void' where there is no good, and 'empty' where there is no truth. Consequently there is 'thick darkness', or stupidity and lack of knowledge about anything that has to do with faith in the Lord and so anything that has to do with spiritual and celestial life. This kind of person is described by the Lord through Jeremiah,

My people are foolish, they know Me not; they are stupid children, having no understanding; they are wise to do evil, and know not how to do good. I looked to the earth, and, behold, a void and an emptiness; and towards the heavens, and they had no light. Jeremiah 4:22-23, 25.
