Elymas (question from New Testament)

It is written:

This is in Acts 13:6-8 according to the English Standard Version (bolding mine). Every version says basically the same thing.

What does the bold part mean? How does Elymas mean Bar-Jesus? In what language?

My Strong’s Concordance says that Bar-Jesus means the Son of Jesus/Joshua. Elymas means “wizard”. My guess is that Bar-Jesus was his real name, and they called him Elymas in the way someone might say “the midwife” to refer to someone whose profession was well-known in a small town.
