“What’s in the well comes up in the bucket” (proverb)

“What’s in the well comes up in the bucket” is a metaphor meaning that what’s in someone’s heart will come out of the mouth. “What is in the well will be in the bucket; what is in the warehouse will be in the shop” was cited in print in 1833. There appears to be a large time gap until the 1990s, when the saying became popular again in print.
 
The saying is sometimes attributed to a farmer from Tennessee or from Texas, but the saying cannot be traced to any specific state.
