Hypocrisy - Ananias and Sapphira - Audio
After Barnabas sold land and donated the proceeds (Chapter 4), husband and wife Ananias and Sapphira thought they'd do the same. The only problem was they kept part of the proceeds and gave the rest to Peter, making people believe that what they gave was all they received. Peter told Ananias that he lied to the Holy Spirit, at which time he collapsed dead on the floor. A few hours later his wife came in, and when confronted with what they'd done, she died as well.
