Origen

“ But he who has been weaned, like Isaac, [7] worthy of the good cheer and reception which Abraham gave at the weaning of his son, would seek here and in every Scripture food which is different, I think, from that which is meat, indeed, but is not solid food, and from what are figuratively called herbs, which are food to one who has been weaned and is not yet strong but weak, according to the saying, “He that is weak eateth herbs.” ”

“ Now this interpretation about the three Apostles not tasting of death until they have seen Jesus transfigured, is adapted to those who are designated by Peter as “new-born babes longing for the reasonable milk which is without guile,” [5] to whom Paul says, “I have fed you with milk, not with meat,” [6] etc. Now, too, every interpretation of a text which is able to build up those who cannot receive greater truths might reasonably be called milk, flowing from the holy ground of the Scriptures, which flows with milk and honey. ”
