Augustine of Hippo

(Tr. xlix. 27) Caiaphas prophesied of the Jewish nation alone; in which nation were the sheep, of which our Lord says, I am not sent but unto the lost sheep of the house of Israel. (Matt. 15:34) But the Evangelist knew that there were other sheep, not of this fold, which were to be brought in, and therefore adds, And not for that nation only, but also that He should gather together in one the children of God that were scattered abroad; i. e. those who were predestined to be so: for as yet there were neither sheep, nor children of God.
