For truly my words shall not be false - This is designed to conciliate attention. It is a professed purpose to state nothing but truth. Even in order to vindicate the ways of God he would state nothing but what would bear the most rigid examination. Job had charged on his friends a purpose "to speak wickedly for God;" to make use of unsound arguments in vindicating his cause, (see the notes at Job 13:7-8), and Elihu now says that "he" will make use of no such reasoning, but that all that he says shall be founded in strict truth.
He that is perfect in knowledge is with thee - This refers undoubtedly to Elihu himself, and is a claim to a clear understanding of the subject. He did not doubt that he was right, and that he had some views which were worthy of their attention. The main idea is, that he was of "sound" knowledge; that his views were not sophistical and captious; that they were founded in truth, and were worthy, therefore. of their profound attention.
My words shall not be false - My words shall be truth without falsity.
He that is perfect in knowledge is with thee - "The perfection of knowledge is with thee." Thou art a sensible, well-informed man, and will be able to judge of what I say.
For truly my words [shall] not [be] false: he that is (b) perfect in knowledge [is] with thee.
(b) You will perceive that I am a faithful instructor, and that I speak to you in the name of God.
For truly my words shall not be false,.... But strictly true; he would take the utmost care to say nothing but the truth, with the greatest impartiality and sincerity, so that what was said might be depended upon; truth spoken briefly, clearly, and on so important a subject as the righteousness of God, deserved attention;
he that is perfect in knowledge is with thee; meaning either God, whose knowledge is perfect, who knows all persons and things; knows himself, his nature, persons, and perfections; his thoughts, counsels, and purposes; all his creatures, angels and men; the hearts of all men, their thoughts, words, and works; he, the omniscient and omnipresent God was with Job, from whose presence there is no fleeing; and therefore it became him to be careful of his thoughts, words, and actions; that he did not entertain any unbecoming thoughts of God, and say anything unworthy of him, or do anything that tended to his dishonour; since he was present with him, and nothing could escape his notice: or else Elihu means himself; suggesting, that he who undertook to speak for God and plead his cause, and clear him from the charge of unrighteousness, was no novice, but one that thoroughly understood the point in hand; and though no man is perfect in knowledge in an absolute sense, yet may be in comparison of others; or however may be upright and sincere in his knowledge; which sense the word used often has; and so it may signify, that as he was a sincere searcher after knowledge, and had through divine goodness attained to a competent share of it, even of sound and not superficial knowledge, he should be honest and upright in the communication of it; and this he might choose to observe the more, to excite the attention of Job to what he had to say; though it may be the truest reading of the words is, "perfect knowledge" or "perfection of knowledge is with thee" (k), that is, in his own apprehension, so Jarchi; and may be understood either ironically, or rather really, insinuating that Job was a man of such consummate wisdom and knowledge, that he would easily see the force of his reasonings, and the justness of them, and acquiesce in them; and having thus prefaced his discourse, he next enters upon his subject.
(k) "scientiae perfectae tecum"; so some in Bar Tzemach.
I will not "speak wickedly for God," as the friends (Job 13:4, Job 13:7-8) --that is, vindicate God by unsound arguments.
he that is perfect, &c.--Rather, as the parallelism requires, "a man of integrity in sentiments is with thee" (is he with whom thou hast to do). Elihu means himself, as opposed to the dishonest reasonings of the friends (Job 21:34).
He, &c. - Thou hast to do with a God of perfect knowledge, by whom all thy words and actions are weighed.
