ûr-bā?nus (Οὐρβανός, Ourbanós; the King James Version Urbane): A common slave name. Gifford says that it is found ?as here, in juxtaposition with Ampliatus, in a list of imperial freedmen, on an inscription, 115 AD.? He was a member of the Christian community at Rome to whom Paul sent greetings. Paul calls him ?our fellow-worker in Christ? (Rom_16:9). ?The 'our' (as opposed to 'my,' Rom_16:3) seems to suggest that all Christian workers had a common helper in Urbanus? (Denney).
