“And when they saw some of his disciples eat bread with defiled, that is to say, with unwashen, hands, they found fault.”
King James Version (KJV)
Mr 7:2 Eat bread with defiled . . . hands. Not dirty, but "unwashed". The "tradition of the elders" (Mt 15:2 Mr 7:3,5) required them to always wash before eating lest they might have touched something ceremonially unclean.
