Jesus doesn’t have a name in the Old Testament. He didn’t exist until he was born of Mary. He was named by the angel Gabriel in the New Testament.
Matthew 1:21 And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
Jesus is the Greek form of the Hebrew ‘Joshua’ which means ‘God saves’.
