'Names' in the Bible

They entered the city, and they went up to the upper room which was now their fixed place for meeting. Their names were Peter and John, James and Andrew, Philip and Thomas, Bartholomew and Matthew, James the son of Alphaeus, Simon the Zealot, and Judas the brother of James.

So two names were proposed, Joseph called Bar-sabbas--and surnamed Justus--and Matthias.

But since these are questions about words and names and your Law, you yourselves must see to them. I refuse to be a judge in such matters."
