Mark 7:3, 5, 8, 13

(For the Pharisees and all the Jews do not eat unless they wash their hands properly, holding to the tradition of the elders

You leave the commandment of God and hold to the tradition of men.”

thus making void the word of God by your tradition that you have handed down. And many such things you do.”
