A.T. Robertson Commentary Luke 22:25

"And he said unto them, The kings of the Gentiles have lordship over them; and they that have authority over them are called Benefactors." — Luke 22:25 (ASV)

Have lordship over (κυριευουσιν). From κυριος. Common verb, to lord it over.

Benefactors (ευεργετα). From ευ and εργον. Doer of good. Old word. Here only in the N.T. Latin Benefactor is exact equivalent.
