Now Samuel didn't yet know Yahweh, neither was the word of Yahweh yet revealed to him.
neither was the word of the Lord yet revealed unto him; what of the written word that was in being he had, and read, as the law of Moses; but the meaning is, that no word of prophecy of the Lord was revealed unto him, as the Targum; he never had prophesied as yet, and knew not the form and manner of prophecy, as the above writer observes, or what methods God took to reveal himself, his mind and will, to men, at least not this by an audible voice.
