In the New Testament, the governor actually asks the crowd "do you want a pardon for Yeshua or Yeshua Bar Abbas", Bar Abbas meaning son of Abbas, a common naming convention. The text officially goes "do you want a pardon for Jesus or Barabbas?"
This is still used today by Jews for Hebrew names. "Bar", the Aramaic word for "son", has in Hebrew its counterpart "ben" ("bat" for women). So your Hebrew name is eg "David ben Benjamin", David son of Benjamin. This is used anywhere to address you in Hebrew, eg for bar/bat mitzvahs, calling up to give blessings in synagogue, headstones, on your ketubah (Jewish marriage license), etc
