In the chair of Moses. Reasons were not wanting for inserting here what Luke relates at a different place. Besides that the doctrine is the same, I have no doubt that Luke, after having said that the scribes were sharply and severely reproved by our Lord, added also the other reproofs which Matthew delayed till the proper place; for already we have frequently seen that the Evangelists, as occasion required, collected into one place various discourses of Christ. But as the narrative of Matthew is more full, I choose rather to take his words as the subject of exposition. Our Lord gives a general exhortation to believers to beware of conforming their life to the wicked conduct of the scribes, but, on the contrary, to regulate it by the rule of the Law which they hear from the mouth of the scribes; for it was necessary (as I have lately hinted) that he should reprove many abuses in them, that the whole people might not be infected. Lest, through their crimes, the doctrine of which they were the ministers and heralds should be injured, he enjoins believers to attend to their words, and not to their actions; as if he had said, that there is no reason why the bad examples of pastors should hinder the children of God from holiness of life. That the word scribes, agreeably to the Hebrew idiom, denotes the teachers or expounders of the Law, is well known; and it is certain that Luke calls the same persons lawyers [1] Now our Lord refers peculiarly to the Pharisees, who belonged to the number of the scribes, because at that time this sect held the highest rank in the government of the Church, and in the exposition of Scripture. For we have formerly mentioned that, while the Sadducees and Essenes preferred the literal interpretation of Scripture, the Pharisees followed a different manner of teaching, which had been handed down, as it were, to them by their ancestors, which was, to make subtle inquiries into the mystical meaning of Scripture. This was also the reason why they received their name; for they are called Pherusim, that is, expounders. [2] And though they had debased the whole of Scripture by their false opinions, yet, as they plumed themselves on that popular method of instruction, their authority was highly esteemed in explaining the worship of God and the rule of holy life. The phrase ought, therefore, to be thus interpreted: "The Pharisees and other scribes, or, the scribes, among whom the Pharisees are the most highly esteemed, when they speak to you, are good teachers of a holy life, but by their works they give you very bad instructions; and therefore attend to their lips rather than to their hands." It may now be asked, Ought we to submit to all the instructions of teachers without exception? For it is plain enough, that the scribes of that age had wickedly and basely corrupted the Law by false inventions, had burdened wretched souls by unjust laws, and had corrupted the worship of God by many superstitions; but Christ wishes their doctrine to be observed, as if it had been unlawful to oppose their tyranny. The answer is easy. He does not absolutely compare any kind of doctrine with the life, but the design of Christ was, to distinguish the holy Law of God from their profane works. For to sit in the chair of Moses is nothing else than to teach, according to the Law of God, how we ought to live. And though I am not quite certain whence the phrase is derived, yet there is probability in the conjecture of those who refer it to the pulpit which Ezra erected, from which the Law was read aloud, (Nehemiah 8:4.) Certainly, when the Rabbis expounded Scripture, those who were about to speak rose up in succession; but it was perhaps the custom that the Law itself should be proclaimed from a more elevated spot. That man, therefore, sits in the chair of Moses who teaches, not from himself, or at his own suggestion, but according to the authority and word of God. But it denotes, at the same time, a lawful calling; for Christ commands that the scribes should be heard, because they were the public teachers of the, Church. The Papists reckon it enough, that those who issue laws should possess the title and occupy the station; for in this way they torture the words of Christ to mean, that we are bound to receive obediently whatever the ordinary prelates of the Church enjoin. But this calumny is abundantly refuted by another injunction of Christ, when he bids them beware of the leaven of the Pharisees, (Matthew 16:6.) If Christ pronounces it to be not only lawful, but even proper, to reject whatever of their own the scribes mingle with the pure doctrine of the Law, certainly we are not bound to embrace, without discrimination or the exercise of judgment, whatever they are pleased to enjoin. Besides, if Christ had intended here to bind the consciences of his followers to the commandments of men, there would have been no good ground for what he said in another passage, that it is in vain to worship God by the commandments of men, (Matthew 15:9.) Hence it is evident, that Christ exhorts the people to obey the scribes, only so far as they adhere to the pure and simple exposition of the Law. For the exposition of, Augustine is accurate, and in accordance with Christ's meaning, that, "the scribes taught the Law of God while they sat in the chair of Moses; and, therefore, that the sheep ought to hear the voice of the Shepherd by them, as by hirelings." To which words he immediately adds: "God therefore teaches by them; but if they wish to teach any thing of their own, refuse to hear, refuse to do them." With this sentiment accords what the same writer says in his Fourth Book of Christian Doctrine: "Because good believers do not obediently listen to any sort of man, but to God himself; therefore we may profitably listen even to those whose lives are not profitable." It was, therefore, not the chair of the scribes, but the chair of Moses, that constrained them to teach what was good, even when they did not do what was good. For what they did in their life was their own; but the chair of another man did not permit them to teach what was their own.

Scribes and Pharisees - See the notes at Matthew 3:7.
Moses' seat - Moses was the great legislator of the Jews. By him the Law was given. The office of explaining that Law among the Jews devolved on the scribes and Pharisees. In the synagogues they sat while expounding the Law, and rose when they read it. By "sitting in the seat of Moses" we are to understand authority to teach the Law; or, as he taught the nation by giving the Law, so they taught it by explaining it.

The scribes and the Pharisees sit in Moses' seat - Εκαθισαν. - They sat there formerly by Divine appointment: they sit there now by Divine permission. What our Lord says here refers to their expounding the Scriptures, for it was the custom of the Jewish doctors to sit while they expounded the law and prophets, (Matthew 5:1; Luke 4:20-22), and to stand up when they read them.
By the seat of Moses, we are to understand authority to teach the law. Moses was the great teacher of the Jewish people; and the scribes, etc., are here represented as his successors.

(1) Saying, The scribes and the Pharisees (a) sit in Moses' seat:
(1) We ought to listen to whatever we are truly taught from the word of God, even by wicked teachers, but in a way so that we abstain from their evil behaviour.
(a) Because God appointed the order, the Lord would therefore have his word to be heard even from the mouth of hypocrites and hirelings.

Saying, the Scribes and Pharisees,.... The Persic version adds, the priests: but Christ does not here speak of the sanhedrim, or grand council of the nation, and of their legislative power; but of those that were the teachers of the people, and the interpreters of the law; and of those, who, though they corrupted the word with their glosses and traditions, yet retained some truth, and at least came nearer truth, than the Sadducees; who therefore are omitted, and only Scribes and Pharisees mentioned, who gave the literal and traditional sense of the Scriptures; of whom he says, they
sit in Moses's seat: not that they were his successors in his office as a legislator and mediator; though the Persic version reads it, "sit in the place and chair of Moses"; but they read his law, and explained it to the people: this post and place, as yet, they kept in the office they were, and were to continue; and the people were to regard them so far as they spoke consistent with the law, until it had its full accomplishment in Christ. The allusion is not to the chairs in which the sanhedrim sat in trying and determining causes, but to those in which the doctors sat when they expounded the law; for though they stood up when they read the law, or the prophets, they sat down when they preached out of them: this custom of the synagogue was observed by our Lord; see Luke 4:16.

Saying, The scribes and the Pharisees sit--The Jewish teachers stood to read, but sat to expound the Scriptures, as will be seen by comparing Luke 4:16 with Matthew 23:20.
in Moses' seat--that is, as interpreters of the law given by Moses.

The scribes and the Pharisees. Associated because almost all the scribes were of the sect of Pharisees. The scribes, the Jewish scholars, the theologians and lawyers, would naturally be of the religious sect.
Sit in the Moses' seat. Are the expounders of the law of Moses.

The scribes sit in the chair of Moses - That is, read and expound the law of Moses, and are their appointed teachers.
