And this spake he not of himself,.... Not of his own devising and dictating, but by the Spirit of God; as a wicked man sometimes may, and as Balaam did; the Spirit of God dictated the words unto him, and put them into his mouth; nor did he use them in the sense, in which the Holy Ghost designed them:but being high priest that year; by his office he was the oracle of God, and was so esteemed by the people, and therefore a proper person to be made use of in this way; and especially being high priest that year, in which the priesthood was to be changed, and vision and prophecy to be sealed up:he prophesied; though he did not know he did, as did Pharaoh, Ex 10:28, and the people of the Jews, Mt 27:25.
