2:28-32 When Mary and Joseph brought Jesus to the temple to be consecrated to God, they met an old man who told them what their child would become. Simeon's song is often called the Nunc Dimittis, because these are the first words of it's Latin translation. Simeon could die in peace because he had seen the Messiah.
2:32 The Jews were well acquainted with the Old Testament prophecies that spoke of the Messiah's blessings to their nation. They did not always give equal attention to the prophecies saying that he would bring salvation to the entire world, not just the Jews (see, for example, Isaiah 49:6). Many thought that Christ had come to save only his own people. Luke made sure his Greek audience understood that Christ had come to save all who believe, Gentiles as well as Jews.
