6 And he said to them, "Well did Isaiah prophesy of you hypocrites, as it is written, "'This people honors me with their lips, but their heart is far from me; 7 in vain do they worship me, teaching as doctrines the commandments of men.' 8 You leave the commandment of God and hold to the tradition of men." 9 And he said to them, "You have a fine way of rejecting the commandment of God in order to establish your tradition! 10 For Moses said, 'Honor your father and your mother'; and, 'Whoever reviles father or mother must surely die.' 11 But you say, 'If a man tells his father or his mother, "Whatever you would have gained from me is Corban"' (that is, given to God)[1]-- 12 then you no longer permit him to do anything for his father or mother, 13 thus making void the word of God by your tradition that you have handed down. And many such things you do."

Commentary on Mark 7:1-13
(Read Mark 7:1-13)
One great design of Christ's coming was, to set aside the ceremonial law; and to make way for this, he rejects the ceremonies men added to the law of God's making. Those clean hands and that pure heart which Christ bestows on his disciples, and requires of them, are very different from the outward and superstitious forms of Pharisees of every age. Jesus reproves them for rejecting the commandment of God. It is clear that it is the duty of children, if their parents are poor, to relieve them as far as they are able; and if children deserve to die that curse their parents, much more those that starve them. But if a man conformed to the traditions of the Pharisees, they found a device to free him from the claim of this duty.
