'White washed' in the Bible

"A curse on you, you hypocritical scribes and Pharisees, for you are like white-washed tombs, which look beautiful on the outside, but inside are full of dead people's bones and everything that is unclean!

Then Paul said to him, "You white-washed wall, God will strike you! Do you sit as a judge to try me in accordance with the law and yet in violation of the law you order them to strike me?"
