Adam Clarke Bible Commentary
These ten times - The exact arithmetical number is not to be regarded; ten times being put for many times, as we have already seen. See particularly the note on Gen 31:7 (note).
Ye make yourselves strange to me - When I was in affluence and prosperity, ye were my intimates, and appeared to rejoice in my happiness; but now ye scarcely know me, or ye profess to consider me a wicked man because I am in adversity. Of this you had no suspicion when I was in prosperity! Circumstances change men's minds.
Jamieson-Fausset-Brown Bible Commentary
These--prefixed emphatically to numbers (Gen 27:36).
ten--that is, often (Gen 31:7).
make yourselves strange--rather, "stun me" [GESENIUS]. (See Margin for a different meaning [that is, "harden yourselves against me"]).
John Gill Bible Commentary
And be it indeed that I have erred,.... Which is a concession for argument's sake, but not an acknowledgment that he had erred; though it is possible he might have erred, and it is certain he did in some things, though not in that respect with which he was charged; "humanum est errare", all men are subject to mistakes, good men may err; they may err in judgment, or from the truth in some respect, and be carried away for a while and to some degree with the error the wicked, though they shall be turned from it again; they may err in practice, and wander from the way of God's commandments; and indeed their strayings and aberrations of this sort are so many, that David says, "who can understand his errors?" Psa 19:12; and they may err in words, or make a mistake in speech; but then no man should be made an offender for a word for he must be a perfect man that is free from mistakes of this kind: now Job argues that supposing this to be his case in any of the above instances; yet, says he,
mine error remaineth with myself; I only am chargeable with it, and answerable for it; it is nothing to you, and why should you trouble yourselves about it? it will not be imputed to you, nor will you suffer on account of it; or, admitting I have imbibed an error, I do not publish it abroad; I keep it to myself; it lies and lodges in my own breast, and nobody is the worse for it: or "let it remain", or "lodge with me" (k); Why should my mistakes be published abroad, and all the world be made acquainted with them? or else this expresses his resolution to abide by what his friends called an error; and then the so is, if this is an error which I have asserted, that God afflicts both good and bad men, and that afflictions are no argument of a man's being an hypocrite and a wicked man, I am determined to continue in it; I will not give it up, I will hold it fast; it shall remain with me as a principle never to be departed from; or it may be rather his meaning is, that this notion he had imbibed would remain with him, and was likely to do so, for anything they had said, or could say to the contrary.
