Mark 7:2-4 HNV

2 Now when they saw some of his talmidim eating bread with defiled, that is, unwashed, hands, they found fault.
3 (For the Perushim, and all the Yehudim, don't eat unless they wash their hands and forearms, holding to the tradition of the Zakenim.
4 They don't eat when they come from the marketplace, unless they bathe themselves, and there are many other things, which they have received to hold to: washings of cups, pitchers, bronze vessels, and couches.)
