Apposition

Can any one give me a little information upon the following passage?— "Quin age, te incolumi potius (potes omnia quando, Nec tibi nequiequam pater est qui sidera torquet) Perficias quodcunque tibi nunc instat agendum." *Hieronym. Vid. Christ.* lib. i. 67. I want to know in what case *te incolumi* is; and, if in the ablative absolute, can any one bring a parallel construction from the writers of the Augustan age, where the law of *apposition* appears to be so far violated?
