In Acts 4:32-5:11, Ananias dies when Peter asks him why he has held some of the proceeds of the sale of his property back from the communal pot. However, it is not made clear that he promised to give them all the money in the first place.

Is this simply implied by the later lie of Sapphira who claims that this was the whole price? Is there anything illuminating from tradition or external Biblical sources? Should this passage be interpretted entirely differently?

So, why did Ananias die?
