Nunc Dimittis - 'let your servant go in peace'

Nunc Dimittis, in the New Testament is "a brief hymn of praise sung by the aged Simeon, who had been promised by the Holy Spirit that he would not die until he had seen the Messiah."

"Now there was a man in Jerusalem called Simeon, who was righteous and devout. He was waiting for the consolation of Israel, and the Holy Spirit was on him. It had been revealed to him by the Holy Spirit that he would not die before he had seen the Lord’s Messiah. Moved by the Spirit, he went into the temple courts. When the parents brought in the child Jesus to do for him what the custom of the Law required, Simeon took him in his arms and praised God, saying:

'Sovereign Lord, as you have promised,
you may now dismiss your servant in peace.'"
