'Extortioner' in the Bible

Let the extortioner catch all that he hath; and let the strangers spoil his labour.

Let mine outcasts dwell with thee, Moab; be thou a covert to them from the face of the spoiler: for the extortioner is at an end, the spoiler ceaseth, the oppressors are consumed out of the land.

But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.
