Question
What is the origin of the word “Amen”? Does it first appear in the Torah? Why do we say it after hearing a blessing? Thank you.

Question
Where did Moshe stand when HaShem spoke to him from the Ohel Mo’ed (tent of meeting): from above the cover of the ark from between the two cherubim which are upon the ark of the testimony? (Leviticus 1:1, Shemot 25:22, Bamidbar 7:89 etc.) Did Moshe stood in the Kodesh — Holy — or in the Kodesh Hakadashim — Holy of Holies — at the times HaShem spoke to him?
