Jesus is the Greek translation of the Hebrew name Joshua. It means, God saves.
The angel Gabriel told Mary to call her son Jesus (Luke 1:31). He did this in order to emphasize the work that Jesus would do, the work of saving God’s people from their sins (Matthew 1:21).
21 And at the end of eight days, when he was circumcised, he was called Jesus, the name given by the angel before he was conceived in the womb.
