He brought them before the king of Moab: and they lived with him all the while that David was in the stronghold.
Verse four. Now the word "hold" is "Masada", and there are those who believe that actually David was there in the hold, or in the fort of Masada which of course was later really developed by king Herod as a winter palace and a fortress. So it is possible David was down in that area of the Dead Sea. It is possible that this is indeed a reference to Masada, but he was there in the hold or in the fort wherever it might have been.
