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. Some went West before North, Jubah used a lion coin for example.

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