Morkoth Riddle Pointing to the 50 Names

The Morkoth, when beaten and pushed, told us that 3 lost tribes were given the 50 names of God. Here's a ridle to help you find them:

Part I:

Issachar's cunning with his hands
Efaim dwells in frozen lands
Asher's woman is Agapie
They bear the secret until they die

This was later deemed "too bogus ever to solve", and the following gloss added:

Encompassed by the Gamma-eye
The Issacharites work and die
They level up when they combine
With other men who toe the line.

When Ephram courted Daughter Senior
Of the emperor from Armenia
Whose foe's cap saved his brain, instead
An older lass turned Ephram's head.

In Asher's name they say he loves,
He loves the demon of the groves.
There where the serpent does not sleep
They lose naught when one takes their sheep.
