Laudator Temporis Acti

Vergil, Aeneid 10.855-856 (Mezentius speaking; tr. H. Rushton Fairclough):

Now I live on, and leave not yet daylight and mankind;
but leave I will.

nunc vivo neque adhuc homines lucemque relinquo.
sed linquam.

relinquo...linquam is an example of compound-simplex verbal iteration, where the simplex verb has the meaning of the preceding compound verb, on which see e.g.:
