PRONUNCIATION: "Zacchaeus (zuh-kee´uhs)" (Harper Collins Bible Dictionary (HBD)) Audio» 

(Commentary) "The tax collectors have been responsive to Jesus, and Jesus has defended his ministry to them against critics....But Jesus has also spoken harsh words about the rich. Zacchaeus is rich; he is also a chief tax collector, not one of the underlings like Levi who sit at toll booths helping to make people like Zacchaeus rich. These mixed signals prevent the audience from making a quick judgment about Zacchaeus based on the narrative so far." (Abingdon New Testament Commentaries (ANTC), p275)
