Final answer:
According to Luke 2:15, the shepherds stated that the Lord had told them about the birth of Jesus, which they learned through the announcement of the angels.
Step-by-step explanation:
According to Luke 2:15, after the angels had left them and gone into heaven, the shepherds said to one another, "Let's go to Bethlehem and see this thing that has happened, which the Lord has told us about." The shepherds are expressing their desire to witness the birth of Jesus, which they were informed of by the angels. This passage is part of the larger narrative of the Nativity of Christ, which includes the announcement to the shepherds by angels of the birth of the Messiah and their subsequent visit to see the baby Jesus in the manger.
