Origen

“ For in either passage of Scripture it is stated that it was in a dream that the angel spoke these words; and that in a dream certain persons may have certain things pointed out to them to do, is an event of frequent occurrence to many individuals,—the impression on the mind being produced either by an angel or by some other thing. Where, then, is the absurdity in believing that He who had once become incarnate, should be led also by human guidance to keep out of the way of dangers? ”

“ And in like manner it was necessary that He should be taken away by His parents, acting under the instructions of an angel from heaven, who communicated to them the divine will, saying on the first occasion, “Joseph, thou son of David, fear not to take unto thee Mary thy wife; for that which is conceived in her is of the Holy Ghost;” [4] and on the second, “Arise, and take the young Child, and His mother, and flee into Egypt; and be thou there until I bring thee word: for Herod will seek the young Child to destroy Him.” ”
