G2a Israelites vs G2b Edomites and Ishmaelites.

Herod and Pharisees however are hidden in G2a as well.

G-FGC31712 aka Fischer, Baker, Hodges, Cunningham, Hall, etc are probably the Herodians.

G2a-Z1903 are probably Pharisees.

The vast majority of G2a are the real Israelites, assimilated into Cimmerians, Scythians, and Medes.

Ephraim vs Elam is just like Israelites vs Edomites, Israelites vs Jebusites, and Israelites vs Canaanites.
