Mark 7:13

13 In this way the teaching you pass on to others cancels out the word of God. And there are many other things like this that you do."

Mark 7:13 In-Context

11 But you teach that if people have something they could use to help their father or mother, but say, "This is Corban' (which means, it belongs to God),
12 they are excused from helping their father or mother.
13 In this way the teaching you pass on to others cancels out the word of God. And there are many other things like this that you do."
14 Then Jesus called the crowd to him once more and said to them, "Listen to me, all of you, and understand.
15 There is nothing that goes into you from the outside which can make you ritually unclean. Rather, it is what comes out of you that makes you unclean."
