Medrash Talpyot At Alef
-The gifts given by Avrahom to these children included the mysteries of the unholy names.
-These names could be used to force angles and demons to do your will.
-There are many levels of impurity. These mysteries given to them by Avrahom also contained truth in them. Avrahom included these to insure they retained some attachment.
-These unclean names were taken by Sara from Egypt when she was locked in Paroah’s palace.-These children traveled east where they became leaders.
-It is from this original wisdom that parts of truth remain in the East.
