23 December - Unto Us is Born a Son
Another carol from the Piae Cantiones collection here, originally titled in Latin Puer nobis nascitur. This carol looks ahead three days from Christmas to the slaughter of the innocents by Herod, whose thirty-year rule was marked by fear of replacement as King. His son Herod Antipas would go on to be a significant figure in the Passion story.
Unto us is born a son,
Christ, from heav'n descending low,
This did Herod sore affray,
Of his love and mercy mild
O and A and A and O,
