5. hearing of the ear-- (Ps 18:44, Margin). Hearing and seeing are often in antithesis (Job 29:11; Ps 18:8).
      seeth--not God's face (Ex 33:20), but His presence in the veil of a dark cloud (Job 38:1). Job implies also that, besides this literal seeing, he now saw spiritually what he had indistinctly taken on hearsay before God's infinite wisdom. He "now" proves this; he had seen in a literal sense before, at the beginning of God's speech, but he had not seen spiritually till "now" at its close.
