I guess I should have been a little more clear. There is no OT type that ties baptism into eternal salvation. There are types of baptism in the OT. The Red Sea crossing being the most famous if you will.Although I agree baptism is not required for eternal salvation there is a type in the OT.
Baptism in the OT is always shown to be after salvation has occurred.
TCGreek don't blow a gasket I was merely giving an example that was timely as per other discussions. Wasn't trying ti incite anything.
