In Genesis 10:6, this signifies all people who are skilled in the knowledges of faith but have no charity; or who are scientifically, or from memory-knowledges, educated in interior knowledges of the Word, and in its very mysteries, but without charity, disregarding them for the rituals of external worship. (Arcana Coelestia 1162)
