The name Heth in the Bible
Etymology of the name Heth
BDB Theological Dictionary declares etymology and meaning of the name Heth unknown, but for the slightly more creative reader, the name Heth looks like it comes from a root rich in meaning, namely חתת (hatat):
From the above we deduct that the name Heth doesn't simply mean Terror, but much rather something like Depleter or Exhauster. In our day and age mister Heth would probably earn the nickname Leech.
For the meaning of the name Heth, NOBSE Study Bible Name List reads Terror. Jones' Dictionary of Old Testament Proper Names reads Dread, Fear.
