Dark
Darkness" is a state without light. "Light" is truth from the Lord, so "darkness" represents a state where truth is lacking. Here's a cogent passage from Arcana Coelestia: "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. (Arcana Coelestia 17)
Ezekiel 47:21-23
21
So you shall divide this land to you according to the tribes of Israel.
22
It shall happen, that you shall divide it by lot for an inheritance to you and to the aliens who live among you, who shall father children among you; and they shall be to you as the native-born among the children of Israel; they shall have inheritance with you among the tribes of Israel.
23
It shall happen, that in what tribe the stranger lives, there you shall give him his inheritance, says the Lord Yahweh.
