(19) And Moses took the bones of Joseph with him; for he had surely sworn the children of Israel, saying: ‘God will surely remember you; and ye shall carry up my bones away hence with you.’
(כה) וַיַּשְׁבַּ֣ע יוֹסֵ֔ף אֶת־בְּנֵ֥י יִשְׂרָאֵ֖ל לֵאמֹ֑ר פָּקֹ֨ד יִפְקֹ֤ד אֱלֹהִים֙ אֶתְכֶ֔ם וְהַעֲלִתֶ֥ם אֶת־עַצְמֹתַ֖י מִזֶּֽה׃ (כו) וַיָּ֣מָת יוֹסֵ֔ף בֶּן־מֵאָ֥ה וָעֶ֖שֶׂר שָׁנִ֑ים וַיַּחַנְט֣וּ אֹת֔וֹ וַיִּ֥ישֶׂם בָּאָר֖וֹן בְּמִצְרָֽיִם׃
(25) And Joseph took an oath of the children of Israel, saying: ‘God will surely remember you, and ye shall carry up my bones from hence.’ (26) So Joseph died, being a hundred and ten years old. And they embalmed him, and he was put in a coffin in Egypt.
(לב) וְאֶת־עַצְמ֣וֹת י֠וֹסֵף אֲשֶׁר־הֶעֱל֨וּ בְנֵי־יִשְׂרָאֵ֥ל ׀ מִמִּצְרַיִם֮ קָבְר֣וּ בִשְׁכֶם֒ בְּחֶלְקַ֣ת הַשָּׂדֶ֗ה אֲשֶׁ֨ר קָנָ֧ה יַעֲקֹ֛ב מֵאֵ֛ת בְּנֵֽי־חֲמ֥וֹר אֲבִֽי־שְׁכֶ֖ם בְּמֵאָ֣ה קְשִׂיטָ֑ה וַיִּֽהְי֥וּ לִבְנֵֽי־יוֹסֵ֖ף לְנַחֲלָֽה׃
(32) And the bones of Joseph, which the children of Israel brought up out of Egypt, buried they in Shechem, in the parcel of ground which Jacob bought of the sons of Hamor the father of Shechem for a hundred pieces of money; and they became the inheritance of the children of Joseph.
Another interpretation: "All of the mitzvah" (Deuteronomy 8:1). If you have began with a commandment, finish all of it. Why? Rabbi Yochanan said, "Anyone who began with a commandment, and afterwards another comes and finishes it, it will be called according to the name of the one who finishes it." From who do you learn [this]? From Moshe. When Israel left Egypt, what is written? "And Moses took the bones of Yosef with him" (Exodus 13:19). All of the people were involved in the plunder and he was taking care of Yosef's bones. He went and stood among the coffins. He called out and said, "Yosef, Yosef, the time has come for the Holy One, blessed be He, to redeem His children. The Divine Presence awaits [you], and Israel and the clouds of glory await [you]. If you will make yourself appear good, but if not, we will be free of your vow." [Whereupon] his coffin immediately stirred, and [Moses] took it and departed. Moshe departed in the wilderness and did not enter the Land. [So] Israel brought in Yosef's bones and buried them. And the commandment was dependent upon them, as it is stated (Joshua 24:32), "The bones of Joseph, which the Children of Israel had brought up from Egypt, were buried at Shekhem." Therefore He said to them, "All of the commandment." Rabbi Yannai said, "Anyone who begins a commandment but does not finish it will bury his wife and two of his sons." From who do you learn [this]? From Yehudah, [where it is stated (Genesis 37:26),] "And Yehudah said to his brothers, 'What gain (betsa) [we get by killing our brother and covering up his blood?]'" They sat to prepare for the bread [and eat their meal]. He said to them, "We are going to kill our brother and then recite a blessing [over the bread]?" As it is stated (Psalms 10:3), "the one that loots (botsea) and blesses reviles the Lord." Hence is it written, "What gain, etc. come, let us sell him to the Yishmaelites" (Genesis 37:26-27). And they listened to him, as he was a king. And had he said to them to bring him back to his father, they would have listened to him. But rather he began with the commandment and did not finish it. Hence one who begins with a commandment should finish all of it. Rabbi Yochanan said, "Anyone who learns Torah but does not fulfill it, it is better for him to have his placenta roll over his face [and smother him as an infant], as it is stated (Deuteronomy 8:1), '[all the mitzvah I am commanding you today] you must guard to keep'" Rabbi Acha said, "Anyone who guards it to keep it, merits that the holy spirit should descend upon him, as stated (Psalms 89:1), 'A psalm of wisdom (maskil) of Eitan the Ezrachite, etc.' And so [too] did He say to Yehoshua (Joshua 1:8), 'Let not this Book of the Torah cease from your mouth... [and then will you comprehend (taskil)].'" Hence is it written, "to guard to keep."
(א) כל המצוה. כפשוטו ומדרש אגדה אם התחלת במצוה גמור אותה, שאינה נקראת אלא על שם הגומרה, שנאמר (יהושע כד, לב) ואת עצמות יוסף אשר העלו בני ישראל ממצרים קברו בשכם, והלא משה לבדו נתעסק בהם להעלותם, אלא לפי שלא הספיק לגמרה וגמרוה ישראל, נקראת על שמם:
(1) If you have begun a commandment, be sure to finish it, for only the one who finishes it get the credit, as it is written (Joshua 24:32), "The children of Israel buried the bones of Joseph, which they had brought up from Egypt, in Sh'khem." But didn't Moses alone bring the bones up (from Egypt)? Rather, (this teaches us that) because he did not manage to finish the commandment (of burying Joseph), the children of Israel did it, it was called by their name.
The word for "bones" in Hebrew being the same as the word for "essence," i.e. עצם. The Torah's report then has a dual meaning, i.e. Moses took Joseph's essence with the Jewish people when they left Egypt. Having acquired Joseph's essence, Moses was later able to give the Jewish people the Torah.
