Jeremiah 35:11

But it came to pass, when Nebuchadnezzar, king of Babylon, came up into the land, his invading army threatening the ancient dwelling-places of the Kenites first, that we said, Come and let us go to Jerusalem for fear of the army of the Chaldeans and for fear of the army of the Syrians, for marauding bands of Syrian tribes took every opportunity to plunder exposed parts of Palestine, 2 Kings 24:2. So we dwell at Jerusalem, making use of the city as a temporary refuge, until they might return to their home-land. The Rechabites thus offered a fine example of willing obedience to the command of their tribal head.
