Mark 7:4-8 NKJV
When they come from the marketplace, they do not eat unless they wash. And there are many other things which they have received and hold, like the washing of cups, pitchers, copper vessels, and couches.
Then the Pharisees and scribes asked Him, “Why do Your disciples not walk according to the tradition of the elders, but eat bread with unwashed hands?”
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.
And in vain they worship Me,
Teaching as doctrines the commandments of men.’
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.”
