Luke 2:29

Now lettest thou (nun apoluei). Present active indicative, Thou art letting. The Nunc Dimittis, adoration and praise. It is full of rapture and vivid intensity (Plummer) like the best of the Psalms. The verb apoluw was common for the manumission of slaves and Simeon here calls himself "thy slave (doulon sou), Lord (Despota, our despot)." See 2 Peter 2:1 .
