Hilary of Poitiers
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.
There is moreover a reason in the subject of His discourse why the Lord should sit in the ship, and the multitude stand on the shore. For He was about to speak in parables, and by this action signifies that they who were without the Church could have no understanding of the Divine Word. The ship offers a type of the Church, within which the word of life is placed, and is preached to those without, and who as being barren sand cannot understand it.
