'Extortion' in the Bible

Woe unto you, scribes and Pharisees, hypocrites! for ye cleanse the outside of the cup and of the platter, but within they are full from extortion and excess.

And the Lord said unto him, Now ye the Pharisees cleanse the outside of the cup and of the platter; but your inward part is full of extortion and wickedness.

I thought it necessary therefore to entreat the brethren, that they would go before unto you, and make up beforehand your aforepromised bounty, that the same might be ready as a matter of bounty, and not of extortion.
