Uz the firstborn of Milcah and Nahor
In Genesis 22:21, Uz, and Buz, his brother, signify various derivative kinds of religion and their modes of worship. (Arcana Coelestia 2864)
Shem, Ham, Japheth, and Canaan
'Shem' can be understood to be internal worship, 'Japheth' is the corresponding external worship, 'Ham' is internal worship corrupted, and 'Canaan' is external worship separate from internal. These people never existed, but the kinds of worship had these names applied to them.
