What does Luke 2:21 mean?
Jesus' upbringing was faithful to God's instructions as given to Israel in the Old Testament. That included circumcision (Leviticus 12:3). At this ceremony, it was traditional for male children to be "officially" given their name. The prior chapter depicted the controversy when John the Baptist was named (Luke 1:59–63). Jesus' designation is no surprise to anyone. When an angel announced His impending birth, the news included a name (Luke 1:31). That moment is recalled in this verse.Messiah's given name is represented in English as Jesus. This is transliterated from the Greek Iēsous. That, in turn, is the Greek version of Yeshua or Yehashua, the same Hebrew name from which we derive Joshua. In Hebrew, the word literally means "Yahweh is salvation." When Joseph had his own angelic encounter (Matthew 1:21), it was explained that this was a reference to Jesus' role as Savior.
In the following verses, Jesus' family will continue to follow traditional Hebrew practice. They will go to the temple for purification, and for a form of infant dedication (Luke 2:22).
