The marauding bands of Chaldeans and their allies had driven the country people in crowds into Jerusalem, and among them the nomad clan of the Rechabites. According to 1 Chron. ii. 55, the Rechabites traced their descent to a certain Hemath, and were a branch of the Kenites, an Edomite tribe dwelling for the most part in the south of Palestine. These Kenites had maintained an ancient and intimate alliance with Judah, and in time the allies virtually became a single people, so that after the Return from the Captivity all distinction of race between Kenites and Jews was forgotten, and the Kenites were reckoned among the families of Israel. In this fusion of their tribe with Judah, the Rechabite clan would be included. It is clear from all the references both to Kenites and to Rechabites that they had adopted the religion of Israel and worshipped Jehovah. We know nothing else of the early history of the Rechabites. The statement in Chronicles that the father of the house of Rechab was Hemath perhaps points to their having been at one time settled at some place called Hemath near Jabez in Judah. Possibly too Rechab, which means "rider," is not a personal name, but a designation of the clan as horsemen of the desert. These Rechabites were conspicuous among the Jewish farmers and townsfolk by their rigid adherence to the habits of nomad life; and it was this peculiarity that attracted the notice of Jeremiah, and made them a suitable object-lesson to the recreant Jews. The traditional customs of the clan had been formulated into positive commands by Jonadab, the son of Rechab, _i.e._ the Rechabite. This must be the same Jonadab who co-operated with Jehu in overthrowing the house of Omri and suppressing the worship of Baal. Jehu's reforms concluded the long struggle of Elijah and Elisha against the house of Omri and its half-heathen religion. Hence we may infer that Jonadab and his Rechabites had come under the influence of these great prophets, and that their social and religious condition was one result of Elijah's work. Jeremiah stood in the true line of succession from the northern prophets in his attitude towards religion and politics; so that there would be bonds of sympathy between him and these nomad refugees. The laws or customs of Jonadab, like the Ten Commandments, were chiefly negative: "Ye shall drink no wine, neither ye nor your sons for ever: neither shall ye build houses, nor sow seed, nor plant vineyards, nor have any: but all your days ye shall dwell in tents; that ye may live many days in the land wherein ye are strangers."
