“Corban ” means
Corban : an offering to God of any sort, bloody or bloodless, but particularly in fulfillment of a vow. The law laid down rules for vows, (1) affirmative; (2) negative. (Leviticus 27:1; Numbers 30:1) ... Upon these rules the traditionists enlarged, and laid down that a man might interdict himself by vow, not only from using for himself, bur from giving to another or receiving from him, some particular object, whether of food or any other kind whatsoever. The thing thus interdicted was considered as corban . A person might thus exempt himself from any inconvenient obligation under plea of corban. It was practices of this sort that our Lord reprehended, (Matthew 15:5; Mark 7:11) as annulling the spirit of the law.
