Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.

Now he that planteth and he that watereth are one: but each shall receive his own reward according to his own labor.

But the planter and the waterer are one; but each shall receive his own reward according to his own labour.

and he who is planting and he who is watering are one, and each his own reward shall receive, according to his own labour,

Now in aim and purpose the planter and the waterer are one; and yet each will receive his own special reward, answering to his own special work.

Now the planter and the waterer are working for the same end: but they will have their separate rewards in the measure of their work.

Now he who plants, and he who waters, are one. But each shall receive his proper reward, according to his labors.

In this the person who plants and the person who waters are one; yet each will receive their own reward in proportion to their own labor.

He that planteth, and he that watereth are one He shows farther, from another consideration, that the Corinthians are greatly to blame in abusing, with a view to maintain their own sects and parties, the names of their teachers, who in the meantime are, with united efforts, aiming at one and the same thing, and can by no means be separated, or torn asunder, without at the same time leaving off the duties of their office. They are one, says he; in other words, they are so linked together, that their connection does not allow of any separation, because all ought to have one end in view, and they serve one Lord, and are engaged in the same work. Hence, if they employ themselves faithfully in cultivating the Lord's field, they will maintain unity; and, by mutual communication, will help each other -- so far from their names serving as standards to stir up contendings. Here we have a beautiful passage for exhorting ministers to concord. Meanwhile, however, he indirectly reproves those ambitious teachers, who, by giving occasion for contentions, discovered thereby that they were not the servants of Christ, but the slaves of vain-glory -- that they did not employ themselves in planting and watering, but in rooting up and burning. Every man will receive his own reward Here he shows what is the end that all ministers should have in view -- not to catch the applause of the multitude, but to please the Lord. This, too, he does with the view of calling to the judgment-seat of God those ambitious teachers, who were intoxicated with the glory of the world, and thought of nothing else; and at the same time admonishing the Corinthians, as to the worthlessness of that empty applause which is drawn forth by elegance of expression and vain ostentation. He at the same time discovers in these words the fearlessness of his conscience, inasmuch as he ventures to look forward to the judgment of God without dismay. For the reason why ambitious men recommend themselves to the esteem of the world is, that they have not learned to devote themselves to God, and that they do not set before their eyes Christ's heavenly kingdom. Accordingly, as soon as God comes to be seen, that foolish desire of gaining man's favor disappears.

Are one - ἕν εἰσιν hen eisin. They are not the same person; but they are one in the following respects:
(1) They are united in reference to the same work. Though they are engaged in different things - for planting and watering are different kinds of work, yet it is one in regard to the end to be gained. The employments do not at all clash, but tend to the same end. It is not as if one planted, and the other was engaged in pulling up.
(2) their work is one, because one is as necessary as the other. If the grain was not planted there would be no use in pouring water there; if not watered, there would be no use in planting. The work of one is as necessary, therefore, as the other; and the one should not undervalue the labors of the other.
(3) they are one in regard to God. They are both engaged in performing one work; God is performing another. There are not three parties or portions of the work, but two. They two perform one part of the work; God alone performs the other. Theirs would be useless without him; he would not ordinarily perform his without their performing their part. They could not do his part it they would - as they cannot make a plant grow; he could perform their part - as he could plant and water without the farmer; but it is not in accordance with his arrangements to do it.
And every man - The argument of the apostle here has reference only to ministers; but it is equally true of all people, that they shall receive their proper reward.
Shall receive - On the Day of Judgment, when God decides the destiny of men. The decisions of that Day will be simply determining what every moral agent ought to receive.
His own reward - His fit, or proper (τον ἴδιον ton idion) reward; that which pertains to him, or which shall be a proper expression of the character and value of his labor - The word "reward" μισθὸν misthon denotes properly that which is given by contract for service rendered; an equivalent in value for services or for kindness; see the note at Romans 4:4. In the Scriptures it denotes pay, wages, recompense given to day-laborers, to soldiers, etc. It is applied often, as here, to the retribution which God will make to people on the Day of Judgment; and is applied to the "favors" which he will then bestow on them, or to the "punishment" which he will inflict as the reward of their deeds. Instances of the former sense occur in Matthew 5:12; 6; Luke 6:23, Luke 6:35; Revelation 11:18; of the latter in 2-Peter 2:13, 2-Peter 2:15 - In regard to the righteous, it does not imply merit, or that they deserve heaven; but it means that, God will render to them that which, according to the terms of his new covenant, he has promised, and which shall be a fit expression of his acceptance of their services. It is proper, according to these arrangements, that they should be blessed in heaven. It would not be proper that they should be cast down to hell - Their original and their sole title to eternal life is the grace of God through Jesus Christ: the "measure," or "amount" of the favors bestowed on them there, shall be according to the services which they render on earth. A parent may resolve to divide his estate among his sons, and their title to any thing may be derived from his mere favor but he may determine that it shall be divided according to their expressions of attachment, and to their obedience to him.

He that planteth and he that watereth are one - Both Paul and Apollos have received the same doctrine, preach the same doctrine, and labor to promote the glory of God in the salvation of your souls. Why should you be divided with respect to Paul and Apollos, while these apostles are intimately One in spirit, design, and operation?
According to his own labor - God does not reward his servants according to the success of their labor, because that depends on himself; but he rewards them according to the quantum of faithful labor which they bestow on his work. In this sense none can say, I have labored in vain, and spent my strength for nought.

Now he that planteth, and he that watereth are one,.... Not in every respect so; they were different as men, they were not the same individual persons, nor in the same office; Paul was an apostle, Apollos only a preacher of the Gospel; nor had they the same measure of gifts, nor did they labour alike, or were of the same usefulness; but they had one and the same commission to preach the Gospel; and the Gospel they preached was the same; and so were their views, aims, and ends, which were the glory of God, and the good of immortal souls; and they had the same love and affection for one another; they were one in their work, judgment, and affection; and which carries in it a strong reason and argument why the members of this church should not contend and divide about them:
and every man shall receive his own reward; either from men, that double honour he is worthy of, maintenance and respect; or rather from God, not a reward of debt, for his labours are by no means meritorious of anything at the hands of God, from whom he has all the grace, strength, and abilities he labours with; but of grace, even the reward of the inheritance, because he serves the Lord Christ; which is by bequest, through the death of the testator, and common to all the children of God, and heirs of glory:
according to his own labour; and not another's; and not according to the success of it, but according to that itself; not that that is the measure of the reward, for the reward infinitely exceeds it; but is that to which God has graciously annexed the promise of the reward, as an encouragement to it.

one--essentially in their aim they are one, engaged in one and the same ministry; therefore they ought not to be made by you the occasion of forming separate parties.
and every man--rather "but every man." Though in their service or ministry, they are essentially "one," yet every minister is separately responsible in "his own" work, and "shall receive his own (emphatically repeated) reward, according to his own labor." The reward is something over and above personal salvation (1-Corinthians 3:14-15; 2-John 1:8). He shall be rewarded according to, not his success or the amount of work done, but "according to his own labor." It shall be said to him, "Well done, thou good and (not successful, but) faithful servant, enter thou into the joy of thy Lord" (Matthew 25:23).

But he that planteth and he that watereth are one - Which is another argument against division. Though their labours are different. they are all employed in one general work, - the saving souls. Hence he takes occasion to speak of the reward of them that labour faithfully, and the awful account to be given by all. Every man shall receive his own peculiar reward according to his own peculiar labour - Not according to his success; but he who labours much, though with small success, shall have a great reward.
Has not all this reasoning the same force still? The ministers are still surely instruments in God's hand, and depend as entirely as ever on his blessing, to give the increase to their labours. Without this, they are nothing: with it, their part is so small, that they hardly deserve to be mentioned. May their hearts and hands be more united; and, retaining a due sense of the honour God doeth them in employing them, may they faithfully labour, not as for themselves, but for the great Proprietor of all, till the day come when he will reward them in full proportion to their fidelity and diligence!
