6 He answered and 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 And in vain they worship Me, Teaching as doctrines the commandments of men.' 8 "For laying aside the commandment of God, you hold the tradition of men--the washing of pitchers and cups, and many other such things you do." 9 He said to them, "All too well you reject the commandment of God, that you may keep your tradition. 10 For Moses said, 'Honor your father and your mother'; and, 'He who curses father or mother, let him be put to death.' 11 But you say, 'If a man says to his father or mother, "Whatever profit you might have received from me is Corban"--' (that is, a gift to God), 12 then you no longer let him do anything for his father or his mother, 13 making the word of God of no effect through your tradition which 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.
