Five  Greek words are translated “heart.”

  • Psuche (also translated spirit or soul) is translated “heart” once (Ephesians 6:6)
  • Apopsucho is translated “hearts failing” in Luke 21:26
  • Sklerokardia is translated “hardness of heart” in Matthew 19:8, Mark 10:5 and 16:14.
  • Kardiognostes is translated “which knows the heart” in Acts 1:24 and 15:8.
  • Kardia is always translated “heart” in 156 places.

Note: In the KJV, Acts 5:33 includes “cut to the heart.”  The original saying was, literally, “sawn in two,” which was a figure of speech of that time meaning the same as “cut to the quick” or “cut to the heart.”  This change probably was made to remove an unfamiliar saying and to make it parallel with Acts 2:37 and 7:54.
