ויכלכל יוסף את אביו ואת אחיו ואת כל בית אביו לחם לפי הטף
And Yosef sustained his father, and his brethren, and all his father's household, with bread, according to the needs of their little ones. (Bereshis 47,12)
Rashi – Yosef sustained each member of the family according to each one’s needs.
Ravaim – In that time period no fruits were available, so was considered part of the years of famine (even though enough food to properly feed Yosef’s family).
Sechel Tov – Intention of the verse “according to the needs of their little ones” indicates that they were fed more than their needs. Children must be given additional food (more than their needs) since they make crumbs and leave over portions of the provided food.
Radak - מכלכל is from the root of the word כל (all) indicates sustenance per the needs for each person. The word is doubled to indicate that they are feed portions fit for a king. Thus, later in Parshas Shmos the Egyptians complained that the Jews were stronger than them since the Egyptians had been sold into servitude to obtain food, while the Jews were fed like kings (for free).
Maaseh Shalom – this verse alludes to the concept that we are entitled to a livelihood in order to provide food to our family. The basic concept is expressed in the Gemara (Taanis 8b) “the One that gives life, should give sustenance.” As stated by the Shulchan haTahor, in bircas hamazon the text reads הזן את הכל (He should sustain all) and does not add ברחמיו (with mercy). The Creator is obligated to sustain us and not be dependent on Mercy. This concept that we are entitled to sustenance is alluded in the verse לחם לפי הטף, since these words have the Gematria of גבור"ה, that HaShem should provide for our needs as a matter of obligation.
Sefes Emes – One is provided with sustenance according to one’s faith, per Tehillim (145,15) ואתה נותן להם את אכלם בעתו. According to the level of one’s faith and reliance in HaShem, so is one rewarded with parnassah. It is known that Yosef alludes to HaShem. The word טף can be also understood as “looking.” Therefore, the verse can mean that HaShem (Yosef) provides sustenance to the Taf (the children of Yisrael) according to the Jews looking to HaShem’s salvation.
Lubavitcher Rebbe – “Who leads the flock of Yosef” (Tehillim 80,2) the people of Yisrael are known by the name Yosef, who sustained all the Jews during the famine. The Medrash (Yalkut Shimoni) explains this verse as a plea to HaShem to conduct Himself towards the Jews as Yosef conducted himself toward the Jews. The Medrash explains the three actions of Yosef as the basis for the request of how HaShem should treat the Jews:
Toras Yosef MedrashRequest to HaShemUnderstanding Why We Deserve the World to ComeYosef assembled food during the years of plenty for the years of famineSo too gather us from this world for the World to ComeWe who perform Mitzvos in a finite manner should merit to share in HaShem’s infinite delight in the World to ComeYosef sustained the Jews according to their deeds (not the initial negative intent of the brothers but the ultimate good)So too sustain us according to our deedsAlthough the intent of deeds may be lacking look upon our actions in performing Mitzvos (all Jews are like a pomegranate)Yosef acted kindly towards his brothers even though they had not acted kindly towards himSo too treat us kindly although we have treated You unkindlyAlthough we also do misdeeds, they ultimately lead to the heightened spiritual service of Baalei Teshuvah
