John Trapp on Job 9:33

Verſe 33. Neither is there any Dayes-man betwixt us] Heb. Any Arguer or Reprover, as Gen. 31.24. We call him an Umpire or Referree, who hath power to reprove and to lay the blame where he findeth it, and finally to compromiſe the buſineſſe. The late Judg Dyer amongſt us, if there came any controverſies of poor men to be tried afore him, would uſually ſay, that either the parties are wilful, or their neighbours without charity, becauſe their ſuits were not quietly ended at home. Now, ſaith Job, as there is no Judg, ſo there is no dayes-man betwixt me and God. If one man ſin againſt another, ſaith good old Eli. the Judg ſhall judg him; but if a man ſin againſt the Lord, who can mediate? 1 Sam. 2.24.

That may lay his hand] To moderate and keep us both in compaſſe, and to compoſe the difference.
