Albert Barnes Commentary Job 22:10

"Therefore snares are round about thee, And sudden fear troubleth thee," — Job 22:10 (ASV)

Therefore snares are round about you - “Snares” were used for catching wild animals and birds, and the word then came to denote any sudden calamity; see (Job 18:8–10). Eliphaz here says, that it “must be” that these calamities came upon Job in consequence of such sins as he had specified. About that he took it for granted there could be no dispute.

And sudden fear - The calamities of Job came upon him suddenly (Job 1:0). It was to this, doubtless, that Eliphaz alluded.
