The aged Simeon's song when he held the infant Christ in the Temple. Sung at the night office (Compline) — the perfect prayer for the end of the day.

The Nunc Dimittis
Lord, now lettest thou thy servant depart in peace,
according to thy word.
For mine eyes have seen thy salvation,
which thou hast prepared
before the face of all people;
to be a light to lighten the Gentiles,
and to be the glory of thy people Israel.
Glory be to the Father, and to the Son, and to the Holy Ghost;
as it was in the beginning, is now, and ever shall be,
world without end. Amen.
