Return, I pray you - That is, return to the argument. Give your attention to it again. Perhaps he may have discerned a disposition in them to turn away from what he was saying, and to withdraw and leave him. Job expresses his belief that he could convince them; and he proposes more fully to state his views, if they would attend to him.
Let it not be iniquity - Let it not be considered as wrong thus to come back to the argument. Or, let it not be assumed that my sentiments are erroneous, and my heart evil. Job means, that it should not be taken for granted that he was a hypocrite; that he was conscious of sincerity, and that he was convinced that he could satisfy them of it if they would lend a listening ear. A similar sentiment he expresses in Job 19:28 :
But ye should say, Why persecute we him?
Seeing the root of the matter is found in me.
My righteousness is in it - Margin, that is, this matter. The sense is, "my complete vindication is in the argument which I propose to state. I am prepared to show that I am innocent." On that account, he wishes them to return and attend to what he proposed to say.

Return, I pray you - Reconsider the whole subject. Do not be offended. Yea, reconsider the subject; my righteousness is in it - my argumentation is a sufficient proof of my innocence.

Return, I pray you,.... From the ill opinion you have of me, and from your hard censures, and entertain other sentiments concerning me: or it may be, upon these words of Job his friends might be rising up as usual to take their leave of him, and break off conversation with him; and therefore he entreats they would return to their seats, and resume the debate, and give a friendly hearing of his case:
let it not be iniquity; either let it not be reckoned an iniquity to return and go on hearing his case; or he entreats that they would take care not to sin in their anger and resentment against him, nor go on to charge him with iniquity: or it may be rendered, "there is no iniquity" (h); that is, it should be found that there was no such iniquity in him as he was charged with; not that he was free from all sin, which no man is, but from that which his friends judged he was guilty of, hypocrisy:
yea, return again; he most earnestly importunes them to return and patiently hear him out:
my righteousness is in it; in the whole of this affair before them, and which was the matter of controversy between them; meaning, not his justifying righteousness before God, but the righteousness of his cause before men; he doubted not but, when things were thoroughly searched into, that his righteousness would be as clear as the light, and his judgment as the noonday; that he should appear to be a righteous man, and his cause a just one; and should stand acquitted and free from all charges and imputations.
(h) "non erit iniquitas", Beza, Mercerus; "nulla", Schultens.

Return--rather, "retract" your charges:
let it not be iniquity--that is, (retract) that injustice may not be done me. Yea retract, "my righteousness is in it"; that is, my right is involved in this matter.

Return - Turn from your former judgment. Iniquity - Or, there shall be no iniquity, in my words. Righteousness - In this cause or matter between you and me; and you will find the right to be on my side.
