I'm currently reading Midrash Rabbah (Bereshis), and I'm intrigued by the story in 1:11, where the children attend the House of the Assembly on a stormy day and ask why there are two forms to the letters mem, nun, zade, peh, and kaf (I've often wondered this myself!!). An explaination is given, describing how the Torah was transmitted "from utterance to utterance, from Faithful to faithful, from Righteous to righteous, from mouth to mouth, from hand to hand" and then it mentions Moses and G-d. However, I'm left still scratching my head how this explains the two forms of these letters and why these letters, specifically? Can someone help clarify this midrash for me? Thanks!
The two forms of the letter "Mem" allude to the word "ma'amar," utterance. The two forms of the letter Mem allude to the Torah being given from a first utterance to a second utterance. Likewise, two Nun's allude to the word "ne'eman," trustworthy, a first trustworthy person and a second trustworthy person. And so forth: two Tzadi's allude to two Tzaddik's, righteous people, two Peh's allude to two Peh's, mouths, and two Kaf's allude to two Kaf's, palms (Maharzu). The bit afterward about God and Moses is explaining these: God's utterance, trustworthiness, righteousness, mouth, and palm to those of Moses.
