Jer 8:8

“How do ye say, we are wise,.... Which they were continually boasting of, though they were ignorant of the judgment of the Lord, and were more stupid than the stork, turtle, crane, and swallow: and the law of the Lord is with us? this was the foundation of their boast, because the law was given to them, and not to the nations of the world, which knew not God, and therefore they must be a wise and understanding people; and this law continued with them, they had it in their synagogues, and in their houses, and read it, and heard, or at least they might and ought to have heard and read it, and in this they trusted; of this character and cast were the Jews in the times of Christ and his apostles, Rom 2:17 to which agrees the Targum, "how say ye, we are wise, and in the law of the Lord we trust?'' Lo, certainly in vain made he it; either the law, which was made or given in vain by the Lord to this people, since they made no better use of it, and valued themselves upon having it, without acting according to it; or the pen of the scribe, which was made by him in vain to write it, as follows: the pen of the scribes is in vain; in vain, and to no purpose, were the scribes employed in writing out copies of the law, when either it was not heard or read, or however the things it enjoined were not put in practice; or the pen of the scribes was in vain, when employed in writing out false copies of the law, or false glosses and interpretations of it, such as were made by the Scribes and Pharisees in Christ's time, and the fathers before them, by whose traditions the word of God was made of none effect: and so the Targum, "therefore, lo, in vain the scribe hath made the lying pen to falsify;'' that is, the Scriptures. The words may be rendered, "verily, behold, with a lie he wrought; the pen: is the lie of the scribes (h).'' (h) "utique ecce, mendacio operatus est; stylus mendacium scribarum est", Schmidt. Approved by Reinbeck. De Accent. Heb. p. 435.”

“law . . . with us-- (Rom 2:17). Possessing the law, on which they prided themselves, the Jews might have become the wisest of nations; but by their neglecting its precepts, the law became given "in vain," as far as they were concerned. scribes--copyists. "In vain" copies were multiplied. MAURER translates, "The false pen of the scribes hath converted it [the law] into a lie." See Margin, which agrees with Vulgate.”

“In spite of this heedlessness of the statutes, the judgment of God, they vainly boast in their knowledge and possession of God's law. Those who said, We are wise, are mainly the priests and false prophets; cf. Jer 8:10, Jer 2:8; Jer 5:31. The wisdom these people claimed for themselves is, as the following clause shows, the knowledge of the law. They prided themselves on possessing the law, from which they conceived themselves to have drawn their wisdom. The second clause, as Hitz. observed, shows that it is the written law that is meant. The law is with us. This is not to be understood merely of the outward possession of it, but the inward, appropriated knowledge, the mastery of the law. The law of Jahveh, recorded in the Pentateuch, teaches not only the bearing towards God due by man, but the bearing of God towards His people. The knowledge of this law begets the wisdom for ruling one's life, tells how God is to be worshipped, how His favour is to be procured and His anger appeased. As against all this, Jeremiah declares: Assuredly the lying pen (style) of the scribes hath made it a lie. Ew., Hitz., Graf, translate ספרים, authors, writers; and the two latter of them take עשׂה = labour: "for a lie (or for deception) hath the lying style (pen) of the writers laboured." This transl. is feasible; but it seems simpler to supply 'תּורת יי: hath made it (the law); and there is no good reason for confining סופר to the original composers of works. The words are not to be limited in their reference to the efforts of the false prophets, who spread their delusive prophecies by means of writings: they refer equally to the work of the priests, whose duty it was to train the people in the law, and who, by false teaching as to its demands, led the people astray, seduced them from the way of truth, and deceived them as to the future. The labours both of the false prophets and of the wicked priests consisted not merely in authorship, in composing and circulating writings, but to a very great extent in the oral teaching of the people, partly by prophetic announcements, partly by instruction in the law; only in so far as it was necessary was it their duty to set down in writing and circulate their prophecies and interpretations of the law. But this work by word and writing was founded on the existing written law, the Torah of Moses; just as the true prophets sought to influence the people chiefly by preaching the law to them, by examining their deeds and habits by the rule of the divine will as revealed in the Torah, and by applying to their times the law's promises and threatenings. For this work with the law, and application of it to life, Jer. uses the expression "style of the Shoferim," because the interpretation of the law, if it was to have valid authority as the rule of life, must be fixed by writing. Yet he did not in this speak only of authors, composers, but meant such as busied themselves about the book of the law, made it the object of their study. But inasmuch as such persons, by false interpretation and application, perverted the truth of the law into a lie, he calls their work the work of the lying style (pen).”
