For the earth, etc. This is a similitude most appropriate to excite a desire to make progress in due time, for as the earth cannot bring forth a good crop in harvest except it causes the seed as soon as it is sown to germinate, so if we desire to bring forth good fruit, as soon as the Lord sows his word, it ought to strike roots in us without delay; for it cannot be expected to fructify, if it be either choked or perish. But as the similitude is very suitable, so it must be wisely applied to the design of the Apostle. The earth, he says, which by sucking in the rain immediately produces a blade suitable to the seed sown, at length by God's blessing produces a ripe crop; so they who receive the seed of the Gospel into their hearts and bring forth genuine shoots, will always make progress until they produce ripe fruit. On the contrary, the earth, which after culture and irrigation brings, forth nothing but thorns, affords no hope of a harvest; nay, the more that grows which is its natural produce, the more hopeless is the case. Hence the only remedy the husbandman has is to burn up the noxious and useless weeds. So they who destroy the seed of the Gospel either by their indifference or by corrupt affections, so as to manifest no sign of good progress in their life, clearly show themselves to be reprobates, from whom no harvest can be expected. The Apostle then not only speaks here of the fruit of the Gospel, but also exhorts us promptly and gladly to embrace it, and he further tells us, that the blade appears presently after the seed is sown, and that growing follows the daily irrigations. Some render thotanen eutheton "a seasonable shoot," others, "a shoot meet;" either meaning suits the place; the first refers to time, the second to quality. [1] The allegorical meanings with which interpreters have here amused themselves, I pass by, as they are quite foreign to the object of the writer.

Footnotes

1 - The word botane here means everything the earth produces service for food. It only occurs here in the New Testament, but is commonly used by the Sept. for sv, which has the same extensive meaning: fruit or fruits would be its best rendering here. The word euthetos is also found in Luke 9:62; 14:34; and it means fit, meet, suitable, or useful; and the last is the meaning given it here by Grotius, Schleusner, Stuart, Bloomfield, and others. It is indeed true that it is used in the Sept. in the sense of seasonable. See Psalm 32:6 -- Ed

For the earth - The design of the apostle by this comparison is apparent. It is to show the consequences of not making a proper use of all the privileges which Christians have, and the effect which would follow should those privileges fail to be improved. He says, it is like the earth. If that absorbs the rain, and produces an abundant harvest, it receives the divine blessing. If not, it is cursed, or is worthless. The design is to show that "if" Christians should become like the barren earth they would be cast away and lost.
Which drinketh in the rain - A comparison of the earth as if it were "thirsty" - a comparison that is common in all languages.
That cometh oft upon it - The frequent showers that fall. The object is to describe fertile land which is often watered with the rains of heaven. The comparison of "drinking in" the rain is designed to distinguish a mellow soil which receives the rain, from hard or rocky land where it runs off.
And bringeth forth herbs - The word "herbs" we now limit in common discourse to the small vegetables which die every year, and which are used as articles of food, or to such in general as have not ligneous or hard woody stems. The word here means anything which is cultivated in the earth as an article of food, and includes all kinds of grains.
Meet for them - Useful or appropriate to them.
By whom it is dressed - Margin, "for whom." The meaning is, on account of whom it is cultivated. The word "dressed" here means "cultivated:" compare Genesis 2:15.
Receiveth blessing from God - Receives the divine approbation. It is in accordance with his wishes and plans, and he smiles upon it and blesses it. He does not curse it as he does the desolate and barren soil. The language is figurative, and must be used to denote what is an object of the divine favor. God delights in the harvests which the earth brings forth; in the effects of dews and rains and suns in causing beauty and abundance; and on such fields of beauty and plenty he looks down with pleasure. This does not mean, as I suppose, that he renders it more fertile and abundant, for:
(1) it cannot be shown that it is true that God thus rewards the earth for its fertility; and,
(2) such an interpretation would not accord well with the scope of the passage.
The design is to show that a Christian who makes proper use of the means of growing in grace which God bestows upon him, and who does not apostatize, meets with the divine favor and approbation. His course accords with the divine intention and wishes, and he is a man on whom God will smile - as he seems to do on the fertile earth.

For the earth which drinketh in the rain - As much as if he had said: In giving up such apostates as utterly incurable, we act as men do in cultivating their fields; for as the ground, which drinketh in the rain by which the providence of God waters it, brings forth fruit to compensate the toil of the tiller, and continues to be cultivated, God granting his blessing to the labors of the husbandman; so,

(3) For the earth which drinketh in the rain that cometh oft upon it, and bringeth forth herbs meet for them by whom it is dressed, receiveth blessing from God:
(3) He lays out the former threatening with a comparison.

For the earth which drinketh in the rain that cometh oft upon it,.... Here the apostle illustrates what he had before been speaking of, by a simile taken from the earth, to which men in general answer, who are of the earth; earthy and unregenerate men and carnal professors are of earthly minds; they are like the earth when it was rude and without form, and cursed by God; and are as insensible as the earth: but the earth is particularly distinguished into that which is fruitful, and which is unfruitful; and the former is spoken of in this verse, to which true believers in Christ agree; who are the good ground, into which the seed of God's word is received, and brings forth fruit; these are God's tillage or husbandry: and the "rain" that comes upon them may signify either the grace of Christ, which, like rain, is an instance of his sovereignty, and what he alone can give, and not the vanities of the Gentiles; and which he gives to persons undeserving of it; and which refreshes, revives, and makes fruitful: or else Christ himself, Psalm 72:6 whose first coming was like rain much desired, and long expected; and so is his spiritual coming very desirable, delightful, refreshing, and fructifying: or rather his Gospel, Deuteronomy 32:2 which comes from above, and is the means of softening hard hearts, of reviving distressed and disconsolate minds, and of making barren souls fruitful; which is done by coming "oft" upon them, at first conversion, and afterwards, alluding to the former and latter rain; and may refer to the receiving of more grace, even grace for grace, out of Christ's fulness, through the ministration of the word, which is drank in by faith, under the influence of the Spirit of God:
and bringeth forth herbs meet for them by whom it is dressed; God the Father, who is the husbandman, and ministers of the Gospel, who arc labourers under him; and where the Gospel comes in power, it brings forth the fruits of the Spirit, the fruits of righteousness, the fruits meet for repentance; and which are to the glory of God the Father, and are answerable to the means be makes use of, the ministry of the word and ordinances; and no man can bring forth fruit without Christ, his Spirit, and grace: and such earth, or those signified by it,
receiveth blessing from God; both antecedent to all this, and which is the cause of fruitfulness; and as consequent upon it, for such receive more grace, even all the blessings of grace, and at last the blessing of glory; and all this being in a way of receiving, shows it to be of gift, and of pure grace.

the earth--rather as Greek (no article), "land."
which drinketh in--Greek, "which has drunk in"; not merely receiving it on the surface. Answering to those who have enjoyed the privilege of Christian experiences, being in some sense renewed by the Holy Ghost; true alike of those who persevere and those who "fall away."
the rain that cometh oft upon it--not merely failing over it, or towards it, but falling and resting upon it so as to cover it (the Greek genitive, not the accusative). The "oft" implies, on God's part, the riches of His abounding grace ("coming" spontaneously, and often); and, on the apostate's part, the wilful perversity whereby he has done continual despite to the oft-repeated motions of the Spirit. Compare "How often," Matthew 23:37. The rain of heaven falls both on the elect and the apostates.
bringeth forth--as the natural result of "having drunk in the rain." See above.
herbs--provender.
meet--fit. Such as the master of the soil wishes. The opposite of "rejected," Hebrews 6:8.
by whom--rather as Greek, "for (that is, on account of) whom," namely, the lords of the soil; not the laborers, as English Version, namely, God and His Christ (1-Corinthians 3:9). The heart of man is the earth; man is the dresser; herbs are brought forth meet, not for the dresser, by whom, but for God, the owner of the soil, for whom it is dressed. The plural is general, the owners whoever they may be; here God.
receiveth--"partaketh of."
blessing--fruitfulness. Contrast God's curse causing unfruitfulness (Genesis 3:17-18); also spiritually (Jeremiah 17:5-8).
from God--Man's use of means is vain unless God bless (1-Corinthians 3:6-7).

For the earth, etc. These two verses show that treatment depends on what kind of fruit is borne. God sends sunshine and rain on the earth. If it brings forth food for man, it is blessed. But if it brings forth thorns and briers, they are rejected. So God, who blesses our lives, and refreshes them with the Gospel, demands righteous fruit. If they bear thorns, the end is destruction.
