Hilary of Poitiers

This grain then when sown in the field, that is, when seized by the people and delivered to death, and as it were buried in the ground by a sowing of the body, grew up beyond the size of all herbs, and exceeded all the glory of the Prophets. For the preaching of the Prophets was allowed as it were herbs to a sick man; but now the birds of the air lodge in the branches of the tree. By which we understand the Apostles, who put forth of Christ’s might, and overshadowing the world with their boughs, are a tree to which the Gentiles flee in hope of life, and having been long tossed by the winds, that is by the spirits of the Devil, may have rest in its branches.
