Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becomes a tree, so that the birds of the air come and lodge in the branches thereof.
All Commentaries on Matthew 13:32 Go To Matthew 13
Hilary of Poitiers
AD 368
Now, in place of the herb, the preaching of the prophets was given to ailing Israel. But the birds of the air dwell in the branches of the tree that rises high above the ground. We see the apostles as branches stretched out by the power of Christ and overshadowing the world. The people of all nations fly there in the hope of life and, disquieted by the whirling winds—that is, by the breath and blowing force of the devil—they come to rest upon those tree branches.
