Marcos 7

11 but you [Pharisees and scribes] say, ‘If a man tells his father or mother, "Whatever I have that would help you is Corban, (that is to say, already a gift to God)," ’ 12 then you no longer let him do anything for his father or mother [since helping them would violate his vow of Corban]; 13 so you nullify the [authority of the] word of God [acting as if it did not apply] because of your tradition which you have handed down [through the elders]. And you do many things such as that."

The Heart of Man

14 After He called the people to Him again, He began saying to them, "Listen [carefully] to Me, all of you, [hear] and understand [what I am saying]: 15 there is nothing outside a man [such as food] which by going into him can defile him [morally or spiritually]; but the things which come out of [the heart of] a man are what defile and dishonor him.
