Inherit
The Lord created us to be separate from Himself, so that He could love us. He thus allows us to act contrary to His will -- to want what is evil and to believe what is false. When we accept the Lord, though -- by learning what's true and determining to live according to it -- we can let Him place inside us a love for what is good. That is our "inheritance.
Uncle
In Leviticus 20:20; 25:49, the "uncle" signifies consanguinity: that the good and truth of the rational are not to be conjoined, as in a marriage, but as brother and sister. (Arcana Coelestia 2524)
In Jeremiah 32:8, 9, 12, this signifies something spiritual having relation to regeneration, its beginning and its end. (Arcana Coelestia 755[3], Apocalypse Explained 166)
