צא מן התיבה (נח ח:טז)

A person isn’t called a “צדיק” if he isn’t careful to answer “אמן’’ ninety times daily. It should seem then that Noach said Amein ninety times a day since he is referred to as נח איש צדיק. The proof is in the words צא מן התיבה – the word צא equals 91, if you add the “א” – to the next word “מן” – the combination is “צ אמן”. We can transcribe the pasuk to”ויאמר אלוקים לנח” – Hashem told Noach, צא – be careful to answer Amein   צ – אמן – saying it 90 times daily.
