On this website, Boaz (the husband of Ruth, from the Bible) is defined as "swiftness". It actually means "strength is within him", (bo = in him, az= strength) and in Hebrew is spelled BET-VAV-AYIN-ZAYIN (although some people leave out the vav.) My Israeli boyfriend is named Boaz, and it certainly helps him stand out in a crowd. (On our first date, the restaurant manager mistook his name for "barf".) Incidentally, he always asks Americans what their names mean, even though most of us don't know-- Israelis are always named with an eye to meaning.
