Which is the least indeed of all seeds; but when it is grown up, it is greater than all herbs, and becometh a tree, so that the birds of the air come, and dwell in the branches thereof. - Matthew 13:32
The least of all seeds. That is, it is one of the least seeds; but in hot countries it is observed to grow to a considerable height, and to become a bush or a little tree. (Witham)
The gospel of Christ, compared in this verse to the grain of mustard seed, has indeed little show of grandeur and human greatness. St. Paul calls it a scandal to the Jew, and a stumbling block to the Gentile. But Jesus Christ here assures us, that when it has been spread and promulgated by his ambassadors, viz. the apostles, it shall surpass every other mode of instruction both in fame and extent. (St. Ambrose, St. Jerome, St. Augustine)
