“All who heard it
καὶ πάντες οἱ ἀκούσαντες ἐθαύμασαν περὶ τῶν λαληθέντων ὑπὸ τῶν ποιμένων πρὸς αὐτούς·
Luke indicated that everyone who heard the news (καὶ πάντες οἱ ἀκούσαντες) from the shepherds were amazed or marveled (ἐθαύμασαν) at what these shepherds had told them (περὶ τῶν λαληθέντων ὑπὸ τῶν ποιμένων πρὸς αὐτούς). This is the opposite of Mark, who did not want people to know that Jesus was the Messiah. Here everyone was amazed about this new messianic child. Mark had people amazed by the actions and words of Jesus, but Luke has them amazed at Jesus’ very presence.
