Wait a second, that's not even Jesus saying that to his disciples. It's the master talking to his servant within the parable. It's always been in there that the master chastises the servant for not putting his money in the bank to accrue interest while he was away. The parable runs from verse 14 to verse 30. Your information is incorrect and this has nothing to do with the Bible being altered.

Edit: This a perfect case-in-point of taking individual verses out of context and it's exactly why so many people dislike/distrust Christians/Christianity.
