Matthew 12:33-34

Amplified Bible, Classic Edition

³³ Either make the tree sound (healthy and good), and its fruit sound (healthy and good), or make the tree rotten (diseased and bad), and its fruit rotten (diseased and bad); for the tree is known and recognized and judged by its fruit.

³⁴ You offspring of vipers! How can you speak good things when you are evil (wicked)? For out of the fullness (the overflow, the ^[a]superabundance) of the heart the mouth speaks.
