i know that moses and the judism was at the same date of the furouni /but the last left too much remnents of their civilisation // nothing remained from the judism kingdoom /only the religion servive // why ... i do not know

Read about emperor Hadrian resolve to wipe out and erace all traces of our herritage and connection to the land( his Palestina creation replaced Judea,Illia Capitolina replaced Yrushalaim,and a temple for their gods replaced Beit Hamikdash). Having said that...i asume your question is indeed legitimate,and not the standard Muslim/Arab musings about us.

Is ther a hotel to stay for the night in Masada?

but Christian tourists can also see a piece of the True Cross and other saint relics. Muslim tourists can admire a piece of a katyusha rocket. Something for everybody.

There is the Masada Youth Hostel very nice and comfortable BB . and there is another one in Ein Gedi .I have been there and it is lovely. enjoy
