Matthew 15:5

It is a gift [δ ω ρ ο ν]. Rev., given to God. The picture is that of a churlish son evading the duty of assisting his needy parents by uttering the formula, Corban, it is a gift to God. "Whatever that me be by which you might be helped by me, is not mine to give. It is vowed to God." The man, however, was not bound in that case to give his gift to the temple - treasury, while he was bound not to help his parent; because the phrase did not necessarily dedicate the gift to the temple. By a quibble it was regarded as something like Corban, as if it were laid on the altar and put entirely out of reach. It was expressly stated that such a vow was binding, even if what was vowed involved a breach on the law.
