In English language Bibles, this name is normally given as "Telah". "Telach" is a transliteration of the original Hebrew form. The original Telah or Telach was an ancestor of
Joshua, mentioned only in one verse in I Chronicles in the Old Testament. Unfortunately, no original meaning is given for this name in
Who's Who in the Old Testament by
Joan Comay, and it is not mentioned at all in
The Complete Book of Hebrew Baby Names by
Smadar Shir Sidi.
