Luke said that the angel told the shepherds that there would be a sign for them (καὶ τοῦτο ὑμῖν σημεῖον) in order to find this baby child (εὑρήσετε βρέφος) that would be a Savior, Messiah, Christ, and Lord. This baby child would be wrapped in bands of swaddling cloth (ἐσπαργανωμένον), lying in a manger (καὶ κείμενον ἐν φάτνῃ). Instead of the sign of a star, as in Matthew, chapter 2:2, they were told about a place with a manger. These shepherds did not bring any gifts with them, unlike the Magi with their gold, frankincense, and myrrh in Matthew, chapter 2:11.
Yahweh said that he was going to bring a mob against Jerusalem. They would follow the common practice of stoning an adulterous woman. They would cut her into pieces with their swords. They would burn down her houses. They were going to execute judgments on her in the sight of many women. Jerusalem would no longer play the whore. She would not give any gifts. Yahweh would satisfy this fury and jealousy. He would then become calm and not angry any longer.
