John 3:20 For every one that doeth evil hateth the light,

Greek : 

Literal Verse: 

Since anyone accomplishing little has hated this light/knowledge, and he doesn't go towards this light/knowledge so that he isn't embarrassed [by] his activities.

KJV : 

Jhn 3:20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.

Interesting and Hidden Aspects: 

The word translated as "evil" here is not the same word translated as "evil" in the previous verse. The word in the previous verse is the one usually translated as "sin" in the Gospels. The word here is much rarer. Both words do not mean evil. The first means "missing the mark" and the closest English word is "mistake," but it also has the sense of "second rate" and "worthless." The word here has a meaning similar. It means "ordinary", "slight", "paltry," and "mean."

The word translated here as "do" is also fairly rare. Similarly, it isn't the word usually translated as "do" in the Gospels (poieo), which means "to do" in the sense of "make" or "produce." This word has more of a sense of "accomplishing" or "achieving" something.

The word "light" in Greek is a metaphor for knowledge. We see this sense in English as well ("a light went on", "then he saw the light") but the connection is much stronger in Greek.
