"Nunc Dimittis" is a Latin term meaning "Now you dismiss," and refers to a canticle found in the Gospel of Luke 2:29-32. It is spoken by Simeon, a devout man who, upon seeing the infant Jesus in the temple, praises God for allowing him to witness the Messiah before his death. This canticle is often used in Christian liturgy, particularly during evening prayers or services. It expresses themes of fulfillment, peace, and the revelation of salvation, highlighting the significance of Jesus as a light for the nations and glory for Israel.
