Friend, I do thee no wrong - I have fully complied with the contract. We had an agreement: I have paid all that I promised. If I choose to give a penny to another man if he labors little or not at all if I should choose to give all my property away to others, it would not affect this contract with you: it is fully met; and with my own with that on which you have no further claim I may do as I please. So, if Christians are just, and pay their lawful debts, and injure no one, the world has no right to complain if they give the rest of their property to the poor, or devote it to send the gospel to the pagan, or to release the prisoner or the captive. It is their own. They have a right to do with it as they please. They are answerable, not to people, but to God, and infidels, and worldly people, and cold professors in the church have no right to interfere.

Friend, I do thee no wrong - The salvation of the Gentiles can in itself become no impediment to the Jews; there is the same Jesus both for the Jew and for the Greek. Eternal life is offered to both through the blood of the cross; and there is room enough in heaven for all.

But he answered one of them,.... Who was the forwardest and loudest in his complaints, and represented the rest;
and said, friend, I do thee no wrong; by giving all alike, the same privileges and blessings to the last, as to the first, since nothing was withheld from him. And indeed the Lord does no wrong to any, by the distinction which he makes among his creatures: he is righteous in all his ways, and holy in all his works: he does no injury to the evil angels, by choosing the good angels, and confirming them in the estate in which they were created; when the others are reserved in chains of darkness, to the judgment of the great day; or by choosing fallen men, in Christ, and making provisions of grace for them, and not devils: and so there is no unrighteousness in him, nor does he do any wrong to any, when, like the potter, out of the same clay, he makes one vessel to honour, and another to dishonour; any more than when, in a providential way, he gives riches and wealth to some, and withholds them from others; or sends his Gospel, the means of grace to one, and not to another: and still less can he be thought to do wrong to the sons of men, by giving to them alike the same grace and privileges here, and the same happiness and glory hereafter; since neither have any right to what they have, or shall enjoy, and no one has the less for what is given to the other.
Didst thou not agree with me for a penny? That is, to labour in the vineyard all the day for a penny; yea, this agreement was made personally with him, not with a servant, or messenger of his; though if it had, it ought, according to the Jewish canons, to have been abode by, which run thus (b):
"A man says to his messenger, or servant, go and hire workmen for me for three pence; he goes and hires them for four pence: if the messenger says to them, your wages be upon me, he gives them four pence, and takes three pence of the master of the house; he looses one out of his own purse: if he says to them, your hire be upon the master of the house, the master of the house gives them according to the custom of the province: if there are one in the province that hired for three pence, and others that are hired for four pence, he gives them but three pence, "and the murmuring" is against the messenger; in what things? When the work is not known, but when the work is known, and it is worth four pence, the master of the house gives them four pence; but if his messenger does not say to them four pence, they do not labour and do what deserves four pence. The householder says to him, hire me for four pence, and the messenger goes and hires for three pence, though the work deserves four pence, they have but three pence; because that , "they took it upon themselves", (i.e. they agreed for so much,) and their murmuring is against the messenger.''
Thus the argument in the parable proceeds upon the agreement, which ought to be abode by.

But he answered one of them--doubtless the spokesman of the complaining party.
and said, Friend, I do thee no wrong: didst not thou agree with me for a penny? &c.

Go thy way. The householder gave these all he had agreed. They had no ground of complaint but envy.
