“There’s a debate, described in the Talmud, between two rabbis, over what should be done if it’s discovered that a house, or even a palace, was built using a stolen beam as part of its foundation. One rabbi says the entire building must be demolished so that the beam can be returned to its original owners. The other rabbi, the far more pragmatic, says the building can remain standing if the full value of the beam is repaid. Both rabbis make clear that, as soon as it is known that the beam was stolen, those living in the house must do something, they must make amends.”
