Job 30:18

“By the great force [of my disease] is my garment changed, etc.] Either the colour of it, through the purulent matter from his ulcers running down upon it, or penetrating through it; or by reason of it he was obliged to shift himself, and to have a change of raiment very frequently; or the supplement, “of my disease”, may be left out, and the sense be, with great force, through main strength, and with much difficulty, his garment was changed, was got off from him, sticking so close to him, and another put on: it bindeth me about as the collar of my coat; his disease encompassed him about on all sides as the collar or edge of his coat encompassed his neck, and cleaved as close, and was as…”

“of my disease--rather, "of God" (Job 23:6). garment changed--from a robe of honor to one of mourning, literally (Job 2:8; Joh 3:6) and metaphorically [UMBREIT]. Or rather, as SCHUTTENS, following up Job 30:17, My outer garment is changed into affliction; that is, affliction has become my outer garment; it also bindeth me fast round (my throat) as the collar of the inner coat; that is, it is both my inner and outer garment.

UMBREIT makes "God" subject to "bindeth," as in Job 30:19.”

“By the great force of my disease - The words “of my disease” are not in the Hebrew. The usual interpretation of the passage is, that in consequence of the foul and offensive nature of his malady, his garment had become discolored or defiled - changed from being white and clear to filthiness and offensiveness. Some have understood it as referring to the skin, and as denoting that it was so affected with the leprosy, that he could scarcely be recognized. Umbreit supposes it to mean, “Through the omnipotence of God has my white robe of honor been changed into a narrow garment of grief” - trauerkleid. Dr. Good renders it, “From the abundance of the acrimony;” that is, of the fierce or…”

“30:18 God grabs . . . the collar of my coat: The Hebrew in this verse is difficult to translate; it could mean that Job feels like he is in a chokehold and is about to be thrown into the mud (cp. 30:19).”
