Job 22:10

Therefore snares are round about thee - “Snares” were used for catching wild animals and birds, and the word then came to denote any sudden calamity; see Job 18:8. 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. It was to this, doubtless, that Eliphaz alluded.
