Luke 11

Luke 11:38

"When the Pharisee saw it, he was surprised that He had not first ceremonially washed before the meal."
Did Jesus actually break the OT law?

This does not record a violation of any law, since while such washings as indicated are described, they are not prescribed or ordered. Indeed, the whole issue for the Pharisee would be the expectation that Jesus would wash after being around the "unclean" masses in the previous passage. In essence Jesus is defying the Pharisee's personal bigotry against the common people.
