Why does the Bible sometimes say God regretted something?

A few passages use striking language: God "regretted" making humanity before the flood, and later "regretted" making Saul king over Israel. These are honest, plainly stated texts worth taking seriously rather than smoothing over immediately.

The Hebrew word behind "regretted" (nacham) is flexible, and can describe comfort, relenting, or a change of heart depending on context—it doesn't automatically mean "realized a mistake" the way the English word "regret" might suggest.

Ancient and modern interpreters have generally read these passages as describing God's genuine grief and response to human evil in relatable, humanlike terms we can understand—not literally suggesting God lacked foreknowledge or made an error. A smaller number of theologians read the language more directly as involving real change. Either way, these passages convey God taking human sin with real, weighty seriousness rather than cold detachment.
