Rechabites
   the descendants of Rechab through Jonadab or Jehonadab. They
   belonged to the Kenites, who accompanied the children of Israel
   into Palestine, and dwelt among them. Moses married a Kenite
   wife (Judg. 1:16), and Jael was the wife of "Heber the Kenite"
   (4:17). Saul also showed kindness to the Kenites (1 Sam. 15:6).
   The main body of the Kenites dwelt in cities, and adopted
   settled habits of life (30:29); but Jehonadab forbade his
   descendants to drink wine or to live in cities. They were
   commanded to lead always a nomad life. They adhered to the law
   laid down by Jonadab, and were noted for their fidelity to the
   old-established custom of their family in the days of Jeremiah
   (35); and this feature of their character is referred to by the
   prophet for the purpose of giving point to his own exhortation.
   They are referred to in Neh. 3:14 and 1 Chr. 2:55. Dr. Wolff
   (1839) found in Arabia, near Mecca, a tribe claiming to be
   descendants of Jehonadab; and recently a Bedouin tribe has been
   found near the Dead Sea who also profess to be descendants of
   the same Kenite chief.
