Job 33:19

“He is chastened also with pain upon his bed, etc.] This seems to be another way, in which God, according to his eternal purposes, speaks unto men, as the word “also” intimates; namely, by afflictions, and sometimes painful ones; which have a voice in them, and men of wisdom will hearken to it, (<330609>Micah 6:9). Pain here signifies not pain of the mind, or a wounded spirit, which is very afflicting, distressing, and intolerable; but pain of the body, as the next clause shows; and this endured on the bed, it being so great as to confine a man to his bed, or is what he felt there, where he might hope for ease and rest; (see <180713>Job 7:13); and the multitude of his bones with strong…”

“When man does not heed warnings of the night, he is chastened, &c. The new thought suggested by Elihu is that affliction is disciplinary (Job 36:10); for the good of the godly. multitude--so the Margin, Hebrew (Keri). Better with the text (Chetib), "And with the perpetual (strong) contest of his bones"; the never-resting fever in his bones (Psa 38:3) [UMBREIT].”

“He is chastened also with pain - As another means of checking and restraining him from the commission of sin. When the warnings of the night fail, and when he is bent on a life of sin, then God lays him on a bed of pain, and he is brought to reflection there. There he has an opportunity to think of his life, and of all the consequences which must follow from a career of iniquity. This involves the main inquiry before the disputants. It was, why people were afflicted. The three friends of Job had said that it was a full proof of wickedness, and that when the professedly pious were afflicted it was demonstrative of insincerity and hypocrisy. Job had called this position in question, and proved…”

“Pain - The second way whereby God instructs men and excites them to repentance. Job 33:22”

“chastened: Job 5:17, Job 5:18; Deu 8:5; Psa 94:12, Psa 119:67, Psa 119:71; Isa 27:9; Co1 11:32; Rev 3:19 pain: Job 7:4, Job 20:11, Job 30:17; Ch2 16:10, Ch2 16:12; Psa 38:1-8; Isa 37:12, Isa 37:13 Job 33:20”

“19 He is chastened also with pain upon his bed, And with the unceasing conflict of his limbs; 20 And his life causeth him to loathe bread, And his soul dainty meat. 21 His flesh consumeth away to uncomeliness, And his deranged limbs are scarcely to be seen. 22 Then his soul draweth near to the grave, And his life to the destroyers. Another and severer lesson which God teaches man is by painful sickness: he is chastened with pain (בּ of the means) on his bed, he and the vigorous number of his limbs, i.e., he with this hitherto vigorous (Raschi), or: while the multitude of his limbs is still vigorous (Ew). Thus is the Keri ורב to be understood, for the interpretation: and the multitude of his…”
