Proverbs 10:18 says that he who hides hatred with lying lips AND he that speaks slander is a fool. (emphasis mine)
The Hider is one that hates who or what he is talking about, but tells others something entirely different. The listener does not know where or how he really stands.
The Slanderer openly despises the thing or person he talks about, and everyone knows it.
Although apparently different, they are inwardly the same. The similarity between the two is in the heart, where there is hatred. They both seek to do damage. The hate and destruction makes them fools.
They are not god-like, filled with creation, love and true judgment.
