2Tim. 1.18
This parenthesis causes some to allege that Onesiphorus had already been executed, or was dead. But the language does not absolute require this.
In that day .. seems to refer to the judgment day of Christ, thought some think it refers to his judgment day before Nero's court.
Carl Spain observes, "If Onesiphour was awaiting trial, Paul avoids langauge that might be used against him."
