Jerome
Catena Aurea · Matthäusevangelium 13
The same day went Jesus out of the house, and sat by the sea side. And great multitudes were gathered together unto him, so that he went into a ship, and sat; and the whole multitude stood on the shore. And he spake many things unto them in parables, saying, Behold, a sower went forth to sow; And when he sowed, some seeds fell by the way side, and the fowls came and devoured them up: Some fell upon stony places, where they had not much earth: and forthwith they sprung up, because they had no deepness of earth: And when the sun was up, they were scorched; and because they had no root, they withered away. And some fell among thorns; and the thorns sprung up, and choked them: But other fell into good ground, and brought forth fruit, some an hundredfold, some sixtyfold, some thirtyfold. Who hath ears to hear, let him hear.
And it is to be noted, that He spake not all things to them in parables, but many things, for had He spoken all things in parables, the people would have departed without benefit. He mingles things plain with things dark, that by those things which they understand they may be incited to get knowledge of the things they understand not. The multitude also is not of one opinion, but of divers wills in divers matters, whence He speaks to them in many parables, that each according to their several dispositions may receive some portion of His teaching.
