Luke 11:34-38

Your eye is the lamp of your body; when your eye is clear, your whole body also is full of light; but when it is bad, your body also is full of darkness.

So watch out that the light in you is not darkness.

Therefore if your whole body is full of light, without any dark part, it will be wholly illuminated, as when the lamp illuminates you with its light.” Woes upon the Pharisees

Now when He had spoken, a Pharisee *asked Him to have lunch with him; and He went in and reclined at the table.

When the Pharisee saw this, he was surprised that Jesus had not first ceremonially washed before the meal.
