Mark 7:5-8

You are hypocrites, just as he wrote: ‘These people, says God, honour me with their words, but their heart is really far away from me. It is no use for them to worship me, because they teach human rules as though they were God's laws!’ “You put aside God's command and obey human teachings.”
