Desiring to be teachers of the law - That is, to have the credit and reputation of being well versed in the law of Moses, and qualified to explain it to others. This was a high honor among the Jews, and these teachers laid claim to the same distinction.

Understanding neither what they say - That is, they do not understand the true nature and design of that law which they attempt to explain to others. This was true of the Jewish teachers, and equally so of those in the church at Ephesus, who attempted to explain it. They appear to have explained the law on the principles which commonly prevailed among the Jews, and hence their instructions tended greatly to corrupt the faith of the gospel. They made affirmations of what they knew nothing of, and though they made confident observations, yet they often pertained to things about which they had no knowledge. One needs only a slight acquaintance with the manner of teaching among Jewish rabbies, or with the things found in their traditions, to see the accuracy of this statement of the apostle. A sufficient illustration of this may be found in Allen's "Modern Judaism."

Teachers of the law - To be esteemed or celebrated as rabbins; to be reputed cunning in solving knotty questions and enigmas, which answered no end to true religion. Of such the rabbinical teaching was full.

Understanding neither what they say - This is evident from almost all the Jewish comments which yet remain. Things are asserted which are either false or dubious; words, the import of which they did not understand, were brought to illustrate them: so that it may be said, They understand not what they say, nor whereof they affirm. I will give one instance from the Jerusalem Targum, on Genesis 1:15 : And God made two great lights, and they were equal in splendor twenty-one years, the six hundred and seventy-second part of an hour excepted: and afterwards the moon brought a false accusation against the sun, and therefore she was lessened; and God made the sun the greater light to superintend the day, etc. I could produce a thousand of a similar complexion.

Desiring to be teachers of the law,.... They were very fond of being called Rabbi, Rabbi, and styled doctors of the law, and of being thought to have skill in interpreting the law, and good talents in expounding it, and preaching upon it; which was now most in vogue, and gained the greatest applause, when the preaching of the Gospel was treated with contempt, not only by the unbelieving Jews, but by judaizing Christians, and carnal professors,

Understanding neither what they say, nor whereof they affirm: they did not understand the law, the nature and end, the purity and spirituality, and perfection of it, which they were so fond of teaching, and went into many foolish and unlearned questions about it; see 2 Timothy 2:23, and which they as foolishly answered: these are the ignorant and unlearned men, who, notwithstanding their vain show of learning, and pretence to skill in interpreting the law, wrested the Scriptures to their own destruction, and that of others; they were ignorant of the things they talked of, and knew not by what arguments to confirm them, and yet were very bold and confident in their assertions: and generally speaking so it is, that those who can prove least assert most, and that with the greatest assurance.

Desiring (θέλοντες)

The participle is explanatory and confirmatory of the preceding statement: since they desire.

Teachers of the law (νομοδιδάσκαλοι)

oP. It occurs in Luke 5:17 and Acts 5:34. Νόμος is, apparently, the Mosaic law. These teachers may have been arbitrary interpreters of that law, but in what way, cannot be shown.

Understanding (νοοῦντες)

Better, though they understand.

What they say - whereof they affirm (ἃ λέγουσιν - περὶ τίνων διαβεβαιοῦνται)

The latter expression is an advance on the former, as appears not only from the verbs themselves, but from the different pronominal expressions. They know not what they say, nor what kind of things they are of which they speak so confidently. The compound διαβεβαιοῦσωαι to affirm, Pasto. Comp. Titus 3:8. The false teachers announce their errors with assurance.

{6} Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm.

(6) There are none more unlearned, and more impudent in usurping the name of holiness, than foolish babblers, who reason fallaciously.

1:7 Desiring to be teachers of the law. To be teachers of law; there is no article. These aspire to a work for which they are totally unfitted. Who has not met the class of men described?

1:7 Understanding neither the very things they speak, nor the subject they speak of.

7. Sample of their "vain talk" (1Ti 1:6).

Desiring-They are would-be teachers, not really so.

the law-the Jewish law (Tit 1:14; 3:9). The Judaizers here meant seem to be distinct from those impugned in the Epistles to the Galatians and Romans, who made the works of the law necessary to justification in opposition to Gospel grace. The Judaizers here meant corrupted the law with "fables," which they pretended to found on it, subversive of morals as well as of truth. Their error was not in maintaining the obligation of the law, but in abusing it by fabulous and immoral interpretations of, and additions to, it.

neither what they say, nor whereof-neither understanding their own assertions, nor the object itself about which they make them. They understand as little about the one as the other [Alford].

1:5-11 Whatever tends to weaken love to God, or love to the brethren, tends to defeat the end of the commandment. The design of the gospel is answered, when sinners, through repentance towards God and faith in Jesus Christ, are brought to exercise Christian love. And as believers were righteous persons in God's appointed way, the law was not against them. But unless we are made righteous by faith in Christ, really repenting and forsaking sin, we are yet under the curse of the law, even according to the gospel of the blessed God, and are unfit to share the holy happiness of heaven.
