Wherefore then dost thou ask of me - Was ever I wont to give answers that were not dictated by the Lord? It is his counsel alone that I communicate.

Then said Samuel, wherefore then dost thou, ask of me,.... Whom thou knowest to have been a prophet of the Lord, and therefore can say nothing more or less than what comes from him, and is according to his will, if anything at all; the "devil" representing Samuel, whom Saul had called for, and reasons in such language as might be thought to be his own, though sometimes he betrays himself:
seeing the Lord is departed from thee; as Saul himself owned: to which he adds:
and is become thine enemy; to make his case appear still more desperate; for his whole view is to lead him to despair, which shows what sort of spirit he was: though some understand this as spoken of David, and read the words, and "he is with thine enemy" (i); is on his side, and favours his cause; so the Targum,"and he is for the help of a man, whose enmity thou sharest in;''or who is at enmity with thee, meaning David; but now the true Samuel would never have said this, or suggested it, that David was an enemy to Saul, for he was not.
