Are not their tent cords pulled up, so that they die without wisdom?’
Eliphaz, having undertaken to convince Job of the sin and folly of his discontent and impatience, here vouches a vision he had been favoured with, which he relates to Job for his conviction. What comes immediately from God all men will pay a particular deference to, and Job, no doubt, as much as any.
Commenting on Job 4:12-21
their excellency-- (Psa 39:11; Psa 146:4; Co1 13:8). But UMBREIT, by an Oriental image from a bow, useless because unstrung: "Their nerve, or string would be torn away." MICHAELIS, better in accordance with Job 4:19, makes the allusion be to the cords of a tabernacle taken down (Isa 33:20).
Doth not their excellency [which is] in them go away? they die, even without wisdom. (q) That is, before any of them were so wise, as to think of death.
