Psalms 129:7

7With which the mower hath not filled his hand. (116) We have here an additional confirmation of the truth, that although the wicked mount high or elevate themselves, and form an extravagant opinion of their own importance, yet they continue mere grass, not bringing forth any good fruit, nor reaching a state of ripeness, but swelling only with fresh appearance. To make this obvious, the Psalmist sets them in opposition to fruit-bearing herbs, which in valleys and low grounds produce fruit for men. In fine, he affirms that they deserve to be hated or despised of all, whereas commonly every one in passing by the corn fields blesses them and prays for the harvest? (117) Farther, he has borrowed this illustration of his doctrine from the affairs of ordinary life, we are taught that whenever there is a hopeful prospect of a good harvest, we ought to beseech God, whose peculiar province it is to impart fertility to the earth, that he would give full effect to his blessing. And considering that the fruits of the earth are exposed to so many hazards, it is certainly strange that we are not stirred ‘up to engage in the exercise of prayer from the absolute necessity of these to man and beast. Nor does the Psalmist, in speaking of passers by blessing the reapers, speak exclusively of rite children of God, who are truly taught by his word that the fruitfulness of the earth is owing to his goodness; but he also comprehends worldly men in whom the same knowledge is implanted naturally. In conclusion, provided we not only dwell in the Church of the Lord, but also labor to have place among the number of her genuine citizens, we will be able fearlessly to despise all fire might of our enemies; for although they may flourish and have a great outward show for a time, yet they are but barren grass, on which the curse of heaven rests.
