The answer is: Imagine evil

Pro 12:20

In Proverbs 12:20, the idea that "deceit is in the heart of them that imagine evil" speaks volumes about the power of our thoughts and intentions. Let’s think about it a bit deeper! The heart in this verse doesn’t refer just to our feelings — it embodies our core character and motivations. In biblical wisdom literature, your intentions shape your actions, and imagining wickedness can eventually lead to less-than-good outcomes for both the person dreaming up that evil and those around them.

Picture Joseph in Genesis, who faced envy and deceit from his brothers. While they imagined evil against him, it led to some wild family drama. This contrasts with the wisdom of loving-kindness that is encouraged elsewhere in Proverbs, showing that good thoughts breed good actions.

Curious fact: the original Hebrew word for "imagine" (חָשַׁב, chashab) can also mean "to plot." So, the implication isn’t only about daydreaming; it involves active scheming, like plotting malevolence. Fun side-note for you: the name for this book of Proverbs derives from Latin and makes its way back to the root “proverbium,” highlighting sayings meant to impart wisdom — what a legacy!

The slant of wisdom often plants seeds of positivity. If we cultivate good thoughts and intentions—living out things like justice and compassion in everyday scenarios—we can grow a garden of righteous deeds. That's the kind of vision that enriches the community!
