Calcol in the Bible Encyclopedia - ISBE
kal'-kol, kal'-kol (kalkol): Mentioned in 1 Ki 4:31 as one of
the wise men with whom Solomon was compared. The better
orthography is Calcol which the King James Version gives for
the same name in 1 Ch 2:6. In the former passage, Calcol is
the son of Mahol, while in the latter he is called the son of
Zerah of the tribe of Judah, and a brother of Heman and Ethan.
