The document is a Christmas carol describing shepherds hearing angels singing about the birth of Jesus Christ. The angels' singing is echoed by the mountains in reply. The shepherds ask why there is celebration and what they saw, to which the angels respond they should come to Bethlehem to see the newborn king and worship him, who was laid in a manger. The carol ends by asking Mary, Joseph, and the shepherds to lend their aid while hearts are lifted in love for the baby Jesus.
