There is no difference between a house quarantined [for suspicion of tzaraat] and a house that has been declared [to contain tzaraat] except that the quarantined house makes things inside it tamei and the declared house makes things inside it and things behind it tamei. And both cause tuma through entrance. Stones that have tzaraat cause tuma behind them. There is no difference between vows and dedications except that one who vows to consecrate something for the use of the Temple must replace it if it is lost, whereas one who dedicates something and uses it only has to pay for the benefit of the usage.
