Sapphira

Sapphira was the wife of Ananias, who in Acts chapter 5 sold a possession and kept back part of the price, with his wife also knowing about it, laying it at the apostles' feet, presumably claiming it was the entire amount. (At the time, believers would sell possessions and give the proceeds to the apostles for distributing to those in need. ) Peter confronted Ananias about his deceit, at which point Ananias fell down dead. Shortly, his wife came, unaware of her husband's death, and was questioned by Peter. She also similarly lied, whereupon she also died the same way.
