Sabrael is named in the account of Sphendonaêl in F. C. Conybeare’s translation of the Testament of Solomon.
Countering Sphendonaêl
In section 77, the sixth decan describes the afflictions he causes. He says that he retreats when Sabrael is invoked against him.
Sabrael’s name thus appears on the countering side of this encounter in Solomon’s questioning of the spirits.
