For the kingdom of heaven ... - The word “for” shows that this chapter should have been connected with the preceding. The parable was spoken expressly to illustrate the sentiment in the last verse of that chapter: “Many that are first shall be last, and the last shall be first.” The kingdom of heaven means here the church, including, perhaps, its state here and hereafter. See the notes at Matthew 3:2. It has reference to rewards, and the meaning may be thus expressed: “Rewards shall be bestowed in my kingdom, or on my followers, in the same manner as they were by a certain householder - in such a way that the last shall be equal to the first, and the first last.”
A householder - A master of a family. One at the head of family affairs.
His vineyard - No inconsiderable part of Judea was employed in the culture of the grape. Vineyards are often used, therefore, to represent a fertile or well-cultivated place, and hence the church, denoting the care and culture that God has bestowed on it. See the notes at Isaiah 5:7. Compare Jeremiah 12:10. For the manner of their construction, see the notes at Matthew 21:33.

A penny a day - The coin here referred to was a Roman coin, equal in value, at different periods, to 15 cents or 17 cents (7 1/2 d. to 8 1/2 d.) (circa 1880’s). The original denotes the Roman denarius δηνάριον dēnarion, a silver coin, which was originally equivalent to ten ases (a brass Roman coin), from which it gets its name. The consular denarius bore on one side a head of Rome, and an X or a star, to denote the value in ases, and a chariot with either two or four horses. At a later period the casts of different deities were on the obverse, and these were finally superseded by the heads of the Caesars. Many specimens of this coin have been preserved.
It was probably at that time the price of a day’s labor. See Tobit 5:14. This was the common wages of a Roman soldier. In England, before the discovery of the mines of gold and silver in South America, and consequently before money was plenty, the price of labor was about in proportion. In 1351 the price of labor was regulated by law, and was a penny a day; but provisions were of course proportionally cheap, and the avails of a man’s labor in articles of food were nearly as much as they are now.

About the third hour - The Jews divided their days into twelve equal parts, or hours, beginning at sunrise and ending at sunset. This was, therefore about nine o’clock in the morning.
Standing idle in the market-place - A place where provisions are sold in towns. Of course, many resort to such places, and it would be the readiest place to meet persons and find employers. They were not, therefore, disposed to be idle, but were waiting in the proper place to find employers.

Whatsoever is right - Whatsoever it shall appear you can earn. The contract with the first was definite; with this one it depended on the judgment of the employer.

The sixth and ninth hour - That is, about twelve o’clock and three o’clock.

The eleventh hour - About five o’clock in the afternoon, or when there was but one working hour of the day left.

When even was come - That is, when the twelfth hour had come; the day was ended, and the time of payment was come.
The steward - A steward is one who transacts business in the place of another. He was one who had the administration of affairs in the absence of the householder, who provided for the family, and who was entrusted with the payment of laborers and servants. He was commonly the most trusty and faithful of the servants, raised to that station as a reward for his fidelity.
Beginning from the last unto the first - It was immaterial where he began to pay, provided he dealt justly by them. In the parable this order is mentioned to give opportunity for the remarks which follow. Had those first hired been first paid, they would have departed satisfied, and the point of the parable would have been lost.

They received every man a penny - There was no agreement how much they should receive, but merely that justice should be done, Matthew 20:4-5, Matthew 20:7. The householder supposed they had earned it, or chose to make a present to them to compensate for the loss of the first part of the day, when they were willing to work, but could not find employment.

They supposed that they should have received more - They had worked longer - they had been in the heat; they supposed that it was his intention to pay them, not according to contract, but according to the time of the labor.

Murmured - Complained; found fault with.
The goodman of the house - The original here is the same word which in Matthew 20:1 is translated householder, and should have been so translated here. It is the old English way of denoting the father of a family. It expresses no moral quality.

The burden and heat of the day - The burden means the heavy labor, the severe toil. We have continued at that toil in the heat of the day. The others had worked only a little while, and that in the cool of the evening, and when it was fax more pleasant and much less fatiguing.

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.

Take that thine is - Take what is justly due to you what is properly your own.

Is thine we evil because I am good? - The Hebrews used the word evil, when applied to the eye, to denote one envious and malicious, Deuteronomy 15:9; Proverbs 23:6. The eye is called evil in such cases, because envy and malice show themselves directly in the eye. No passions are so fully expressed by the eye as these. “Does envy show itself in the eye? is thine eye so soon turned to express envy and malice because I have chosen to do good?”

So the last shall be first ... - This is the moral or scope of the parable. “To teach this it was spoken.” Many that, in the order of time, are brought last into the kingdom, shall be first in the rewards. Higher proportionate rewards shall be given to them than to others. “To all justice shall be done.” To all to whom the rewards of heaven are promised they shall be given. Nothing shall be withheld that was promised. If, among this number who are called into the kingdom, I choose to raise some to stations of distinguished usefulness, and to confer on them special talents and higher rewards, I injure no other one. They shall enter heaven, as was promised. If, amid the multitude of Christians, I choose to signalize such men as Paul, and Martyn, and Brainerd, and Spencer, and Summerfield - to appoint some of them to short labor but to wide usefulness, and raise them to signal rewards, I injure not the great multitude of others who live long lives less useful and less rewarded. All shall reach heaven, and all shall receive what I promise to the faithful.
Many be called, but few chosen - The meaning of this, in this connection, I take to be simply this: “Many are called into my kingdom; they come and labor as I command them; many of them are comparatively unknown and obscure; yet they are real Christians, and shall all receive the proper reward. A few I have chosen for higher stations in the church. I have endowed them with apostolic gifts or with superior talents, and suited them for wider usefulness. They may not be as long in the vineyard as others; their race may be sooner run; but I have chosen to honor them in this manner, and I have a right to do it. I injure no one, and have a right to do what I will with my own.” Thus explained, this parable has no reference to the call of the Gentiles, nor to the call of aged sinners, nor to the call of sinners out of the church at all. It is simply designed to teach that in the church, among the multitudes who will be saved, Christ makes a difference. He makes some more useful than others, without regard to the time which they serve, and he will reward them accordingly. The parable teaches one truth, and but one; and where Jesus has explained it, we have no right to add to it, and say that it teaches anything else. It adds to the reason for this interpretation, that Christ was conversing about the rewards that should be given to his followers, and not about the numbers that should be called, or about the doctrine of election. See Matthew 19:27-29.
