Comentario citado sobre I Samuel 1:5

והנה נער בוכה, ותחמול עליו, because he was crying she took pity on him. Furthermore, because she saw that he was a circumcised boy, she added: מילדי העברים זה, that it was one of the Hebrew children. We find something parallel in Samuel I 1,5 where we are told ולחנה יתן מנה אחת אפים, that Elkanah would give his wife Chanah a double portion, the reason being explained later with the words: כי את חנה אהב “for he deeply loved Chanah.” This is all very fine, but why does the prophet stress the word אחת in the description מנה אחת אפים, “one portion twice,” instead of writing שתי מנות, “two portions?” The reason is that although she was childless her husband gave her a double portion (only), whereas Peninah, having numerous children received far more than 2 portions. Elkanah compensated Chanah for her childlessness. Here the daughter of Pharaoh reacted to the miserable condition Moses found himself in.

מן הוא, “it is a portion (of food)!” The word is derived from מנה, a gift.” we find the word in Samuel I 1,8 מנה אחת אפים, “a double-portion (of gifts).” Here too the arrival of the manna was a gift for Moses (who had not even had to ask G’d for it). The Torah had to explain this as the Israelites did not know what to make of this new phenomenon. Seeing that they did not know what it was they named it “a gift” (from heaven). Rabbeinu Chananel writes: the words מן הוא mean מאין הוא “where does it come from,” as they did not know its origin.

ויאמרו איש אל אחיו מן הוא?, they said to one another: ”what is it?” some commentators believe that the word מן is derived from the root מנה as in Daniel 1,10 מנה את מאכלכם, “he has provided your food,” although here the word appears in the text before Moses had told the people that this was to serve as their bread. Other commentators link the word to the expression מנה אחת אפים, “a gift of SPECIAL value.” (Samuel I 1,5) The final letter ה is missing in the word מן, according to that interpretation.
