harden heart

The Hebrew that is translated into English as forms of “(to not) harden heart” is translated into other languages with their own vivid idioms; for example, Thai uses “black-hearted” (source: Bratcher / Hattoon, p. 272), Pökoot as “makany kwoghïghitu mötöwekwo”: “do not let become hard your heads” (source: Gerrit van Steenbergen), or Anuak as “make liver strong” (source: Loren Bliese).

See also hardness of heart and see Seat of the Mind for traditional views of “ways of knowing, thinking, and feeling.”
