    • HELPS Word-studies
      • 4456 pōróō (from pōros, a kind of marble) – properly, made of stone; (figuratively) insensible; dull, unperceptive as a rock; calloused (hardened); i.e. unresponsive (dense), completely lacking sensitivity or spiritual perception.
      • From the time of Hippocrates, 4456 (pōróō) means “harden,” like a formed callus which petrifies (cf. DNTT, 2, 153).
      • 4456 (pōróō) was applied to bony formations on the joints (a “callus,” ossification) – hence meaning “to petrify” (as in “covering over with a callus”). 4456 (pōróō) is only used figuratively in the NT meaning “to deaden (dull), to make (render) obtuse (dull, dead)” (Souter).
