The lips of wise people scatter knowledge about

The word "lips" represents what wise people say. The writer speaks of knowledge as if it were seeds that wise people scatter around when they speak. Alternate translation: "The speech of wise people spreads knowledge" (See: rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-metonymy)

not so the hearts of fools

Possible meanings are 1) the word "hearts" is synecdoche for the fools themselves and means that they do not scatter knowledge like wise people do. Alternate translation: "fools do not scatter knowledge about" or 2) fools do not have knowledge in their hearts, with "hearts" being a metonym for the thoughts. Alternate translation: "fools do not understand knowledge" (See: rc://en/ta/man/jit/figs-synecdoche and rc://en/ta/man/jit/figs-metonymy)
