λειτουργέω leitourgeō

A verb for performing a public or official service. In classical Athenian use it can mean supplying a public office at one’s own cost. In biblical Greek it is used of priestly and Levitical service and, more broadly, of service rendered to God or to people. Rom 15:27 uses it with a dative of the persons served, in the phrase about serving in material things. A related verb is used more generally of religious service.
