For by seed here He means His doctrine, and by land, the souls of men, and by the sower, Himself .... For as the sower makes no distinction in the land submitted to him, but simply and indifferently casts his seed; so He Himself too makes no distinction of rich and poor, of wise and unwise, of slothful or diligent, of brave or cowardly; but He discourses unto all, fulfilling His part, although foreknowing the results.
St. John Chrysostom
Homily 44 on Matthew 12, 4th Century
When you see life's pleasures, beware that they might not distract you, for they conceal death's snares. Likewise a fisherman casts not his hook to no purpose. As bait for his hook, the enemy uses the delusion of sensuality to arouse desire, that he might thereby catch men's souls and subject them to himself. A soul which has been caught to serve the enemy's will then serves as a snare for other souls, for it conceals the grief of sin with its apparent delight.
