Job 40:5

“Once have I spoken; but I will not answer, etc.] Some think this refers to what he had just now said of his vileness, he had owned that, and that was all he had to say, or would say, he would give no other answer; Jarchi says, some suppose he has respect to his words in (<180922>Job 9:22); yea, twice; but I will proceed no further; the meaning seems to be, that he who had once and again, or very often, at least in some instances, spoken very imprudently and indecently, for the future would take care not to speak in such a manner: for this confession was not quite free and full; and therefore the Lord takes him in hand again, to bring him to make a more full and ingenuous one, as he does in…”

“Once . . . twice--oftentimes, more than once (Job 33:14, compare with Job 33:29; Psa 62:11): I have spoken--namely, against God. not answer--not plead against Thee.”

“Once have I spoken - That is, in vindicating myself. He had once spoken of God in an irreverent and improper manner, and he now saw it. But I will not answer - I will not now answer, as I had expressed the wish to do. Job now saw that he had spoken in an improper manner, and he says that he would not repeat what he had said. Yea, twice - He had not only offended once, as if in a thoughtless and hasty manner, but he had repeated it, showing deliberation, and thus aggravating his guilt. When a man is brought to a willingness to confess that he has done wrong once, he will be very likely to see that he has been guilty of more than one offence. One sin will draw on the remembrance of another;…”

“Answer - Speak again; I will contend no more with thee. Twice - Often, the definite number being used indefinitely. Job 40:6”

“40:5 Job had nothing more to say; he had no further charges against God, nor would he make a rebuttal.”

“but I will not: Job 34:31, Job 34:32; Rom 3:19 twice: Job 33:14; Kg2 6:10; Psa 62:11 but I will proceed: Jer 31:18, Jer 31:19 Job 40:6”
