Luke 11:38

And when the Pharisee saw it, he wondered that he had not first immersed himself before dinner.

Why do your disciples transgress the tradition of the elders? for they do not wash their hands when they eat bread.

and when they saw some of his disciples eating bread with common, that is, with unwashed hands:

There arose, therefore, a dispute between some of John's disciples and a Jew, about purification.
