Ananias and Sapphira died because of their dishonesty. In the book of Acts in the Bible, Ananias and his wife Sapphira sold a piece of property and agreed to give the proceeds to the early Christian community. However, they secretly kept back some of the money for themselves and only gave a portion to the community, pretending it was the full amount.
When Peter confronted Ananias about his deception, he fell down dead on the spot. Later, when Sapphira arrived and was questioned by Peter, she also fell down dead.
Their deaths were a harsh reminder of the seriousness of lying to God and to the community, and the importance of honesty and integrity in the Christian faith.
