Derived from" day" in the sense of a day of trial (1 Corinthians 4:3 margin). An arbitrator. Job 9:33; "neither is there any daysman betwixt us that might lay his hand upon us both." The umpire in the East lays his hand on both parties to mark his power to adjudicate between them. An arbitrator could have been found on a level with Job; but none on a level with Jehovah, the other Party with whom Job was at issue. We know a Mediator on a level with God, and also on a level with us, the God-man Jesus (1 Timothy 2:5).
