Bede the Venerable — as excerpted in the Catena Aurea on Mark 7:1-13

“(in Marc. 2, 29) The people of the land of Gennesareth, who seemed to be unlearned men, not only come themselves, but also bring their sick to the Lord, that they may but succeed in touching the hem of His garment. But the Pharisees and Scribes, who ought to have been the teachers of the people, run together to the Lord, not to seek for healing, but to move captious questions; wherefore it is said, Then there came together unto him the Pharisees and cerlain of the Scribes, coming from Jerusalem; and when they saw some of his disciples eat bread with common, that is, with unwashen hands, they found fault.”
