Corban

Corban is a Hebrew term meaing 'gift.' It appears only once transliterated at Mk 7:11 (8-13)*:

"You have let go of the commands of God and are holding on to the traditions of men." And he said to them: "You have a fine way of setting aside the commands of God in order to observe your own traditions! For Moses said, 'Honor your father and your mother,' and, 'Anyone who curses his father or mother must be put to death.' But you say that if a man says to his father or mother: 'Whatever help you might otherwise have received from me is Corban', then you no longer let him do anything for his father or mother. Thus you nullify the word of God by your tradition that you have handed down. And you do many things like that."

Corban is here understood as anything that has been set aside to God in fulfilment of a vow, and is, therefore, not available for common use.

*Though Matt 15:3-10 records essentially the same event, the text in Matt does not use the word 'corban.'
