XXeks-tor-shun: This particular word occurs twice in King James Version: Ezek 22:12 (`osheq), and Mt 23:25 (harpage), and indicates that one who is an extortioner is guilty of snatching away from another by strife, greed and oppression that which does not lawfully belong to him. The element of covetousness and usury is involved in the meaning of this word; for it is greedily gotten gain. The publicans were considered as being specially guilty of this sin; this is clear from the Pharisees deprecatory remark: "I am not .... an extortioner ..... as this publican" (Lk 18:11). Paul classes extortion (pleonexia, literally, "over-reaching") among a category of the grossest crimes known to humanity (1 Cor 5:10,11); indeed, so grievous is it that it closes the door of heaven in the face of the one guilty of it (1 Cor 6:10).
