If you put something vile into your mouth
It travels to the stomach then the gut,
And you will then feel sick as it heads south
To soon be shot out through the you-know-what.
The things the mouth spews out is worse than that:
The lie, the filthy jest, the words that hate,
The gossip and the smears, the idle chat,
For from the heart most evil would create.
The dung that leaves the heart defiles a man,
As it’s the fountain which defilement flows.
Then hateful words and deeds the streams that span
Throughout the speaker’s world to decompose.
From out the mouth will spout two noxious things:
Some stomach rot or evil the heart brings.
But those things which proceed out of the mouth
come forth from the heart; and they defile the man.
Matthew 15:18 KJV
