CORBAN
Greek transliteration of the Hebrew “gorban”, “an offering”, meaning anything consecrated or offered to God.
The Jews allowed, and perhaps encouraged, children to consecrate their property to God, and then refuse to help their parents, under the excuse that their property was “corban,” or consecrated.
The Lord reproaches the Jewish authorities for this as one of their traditions, by which they nullified the word of God (Mark 7:11).
