Jeremiah 35:18

"And Jeremiah said unto the house of the Rechabites, thus saith Jehovah of hosts, the God of Israel: Because ye have obeyed the commandment of Jonadab your father, and kept all his precepts, according to all that he commanded you; therefore thus saith Jehovah of hosts, the God of Israel: Jonadab the son of Rechab shall not want a man to stand before me forever."

Attempts to pinpoint the fulfillment of this promise to the Rechabites have been made, but not very convincingly. Nevertheless, we know that God did indeed bless the Rechabites as indicated here. Payne Smith declared that, "Professor Plumptre proved that the prophecy here was literally fulfilled when the Rechabites were incorporated into the tribe of Levi, whose office it was `to stand before Jehovah' (Deuteronomy 10:8)."[17] It is also possible that the firm rejection of alcoholic drinks in the Arab countries today may have come about, in part, because of the influence of the Rechabites. "Even today in Syria and Arabia, there are groups that claim to be Rechabites and that follow the Rechabite rule."[18]
