Job 8:9

New English Translation

⁹For we were born yesterday^[a] and do not have knowledge,
since our days on earth are but a shadow.^[b]

Job 8:9 tn The Hebrew has “we are of yesterday,” the adverb functioning as a predicate. Bildad’s point is that they have not had time to acquire great knowledge because they are recent.
Job 8:9 tn E. Dhorme (Job, 116) observes that the shadow is the symbol of ephemeral things (14:2; 17:7; Ps 144:4). The shadow passes away quickly (116).
