And this will be the sign for you: you will find a baby wrapped in swaddling clothes and lying in a manger.” Bible

“the sign.” It was not “a” sign, as though there were many signs, but “the” particular sign given the shepherds by the angel. In Luke 2:16, this finds its fulfillment when the shepherds find the baby in “the” manger. Cp. Lenski.
