At that time Jesus went on the sabbath day through the grain field; and his disciples were hungry, and began to pluck the ears of grain, and to eat.
All Commentaries on Matthew 12:1 Go To Matthew 12
Hilary of Poitiers
AD 368
We must first point out the beginning of this passage: “At that time Jesus went through the standing grain.” This is set at the time he gave thanks to God the Father for having given salvation to the people. The same meaning is given to what went before (his thanksgiving) and what came after (his walking in the fields). Note the relationships. Spiritually viewed, the land is the world, the sabbath is the day of rest, and the crop is the effect of future believers upon the harvest. Therefore, having gone out to a field on the sabbath, the day of rest under God’s law, he proceeded into this world, to visiting the crop, the sown field of the human race. And since hunger is the craving for human salvation, the disciples hasten to pluck off the ears of corn, namely, the holy people, to get their fill of salvation. But the grain is not yet ready for human consumption. Rather, the crop upholds faith in the events to come. The added power of words completes the sacrament that implies both hunger and fullness.
