From Theological Dictionary of the New Testament
In the NT it occurs only at Mk. 10:42 and par.: οἴδατε ὅτι οἱ δοκοῦντες ἄρχειν τῶν ἐθνῶν κατακυριεύουσιν αὐτῶν καὶ οἱ μεγάλοι αὐτῶν κατεξουσιάζουσιν αὐτῶν. Here its primary sense is that they “exercise power over them.” There is no earthly government without the use of force. But if the reference in οἱ μεγάλοι is not merely to the authorities, it is likely that the word implies the tendency towards compulsion or oppression which is immanent in all earthly power, and not merely in political.
