And on returning from the market, they do not eat unless they wash. And there are many other traditions for them to observe, including the washing of cups, pitchers, kettles, and couches for dining.

Jeremiah 35:5
Then I set pitchers full of wine and some cups before the men of the house of the Rechabites, and I said to them, "Drink some wine."

Matthew 23:25
Woe to you, scribes and Pharisees, you hypocrites! You clean the outside of the cup and dish, but inside they are full of greed and self-indulgence.

Matthew 23:26
Blind Pharisee! First clean the inside of the cup and dish, so that the outside may become clean as well.

Mark 7:8
You have disregarded the commandment of God to keep the tradition of men."

Hebrews 9:10
They consist only in food and drink and special washings--external regulations imposed until the time of reform.

And when they come from the market, except they wash, they eat not. And many other things there be, which they have received to hold, as the washing of cups, and pots, brazen vessels, and of tables.
