Job 33.22-25

I see the Trinity in this passage.

"Yea, his soul draweth near unto the pit, And his life to the destroyers. If there be with him an angel, An interpreter, one among a thousand, To show unto man what is right for him; Then [God] is gracious unto him, and saith, Deliver him from going down to the pit, I have found a ransom. His flesh shall be fresher than a child's; He returneth to the days of his youth" (Job 33.22-25).

God the Father has found the ransom in Jesus. Jesus is the mediator, an angel in the OT (not incarnated yet), extremely rare and correctly interprets the Scriptures. Is. 53 is the most quoted and interpreted passage in the NT. The vigor of youth is the work of the Holy Spirit to renew.
