Mark 7:11
But you say that if anyone declares that what might have been used to help their father or mother is Corban (that is, devoted to God) — the Corban practice allowed a person to declare property or money as dedicated to God (Corban, from the Hebrew qorban meaning offering). Once declared Corban, the property could not be used for other purposes — including supporting aging parents. The practice may have originated as genuine piety but had become, in some applications, a legal device to avoid parental support obligations while retaining personal use of the resources.
