Abdi2, the son of Elam, represents a thought of service to God that is established in an idea of youth and strength (Elam means fully developed, a young man) but is united to a physical or carnal soul quality (he was married to a foreign wife). This carnal idea has to be given up. The Israelites had to separate themselves from their foreign wives and from the children (mixed thoughts) that had come of union with them.
