“And there were shepherds living out in the fields nearby, keeping watch over their flocks at night. An angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were terrified. But the angel said to them, ‘Do not be afraid. I bring you good news of great joy that will be for all the people. Today in the town of David a Savior has been born to you; he is Christ the Lord. This will be a sign to you. You will find a baby wrapped in cloths and lying in a manger’” - Luke 2: 8-12
And then we know a great company of angels began to sing praise to God and blessings of peace to people on earth whom God approved. Next, the shepherds went to see the baby Jesus and began praising God and telling others about what they had seen.
