'Inside' in the Bible

Blind Pharisee, first wash clean the inside of the cup or dish, and then the outside will be clean also.

"Alas for you, Scribes and Pharisees, hypocrites, for you are just like whitewashed sepulchres, the outside of which pleases the eye, though inside they are full of dead men's bones and of all that is unclean.

Foolish men! Did not He who made the outside make the inside also?
