Names carry a meaning. Biblical names are no exception as illustrated by the angel’s message to Joseph (Matthew 1:20-21) about the child Mary was carrying. “…you are to give him the name Jesus, because he will save his people from there sins.”
[Jesus is the Greek form of Joshua which means ‘ The LORD saves’]
