Passage in Vida

Your correspondent A.W. asks for some light on the lines of Vida, *Christiad*, i. 67.: "Quin age, te incolumi potius.... ... Perficias quodcumque tibi nunc instat agendum." He cannot construe "te incolumi." No wonder. Will not all be set right by reading, "Quin age, et incolumi," &c.?
