כל המצוה. כִּפְשׁוּטוֹ; וּמִדְרַשׁ אַגָּדָה אִם הִתְחַלְתָּ בְּמִצְוָה גְּמֹר אוֹתָהּ, שֶׁאֵינָהּ נִקְרֵאת אֶלָּא עַל שֵׁם הַגּוֹמְרָהּ, שֶׁנֶּאֱמַר "וְאֶת עַצְמוֹת יוֹסֵף אֲשֶׁר הֶעֱלוּ בְנֵי יִשְׂרָאֵל מִמִּצְרַיִם קָבְרוּ בִשְׁכֶם" (יהושע כ"ד), וַהֲלֹא מֹשֶׁה לְבַדּוֹ נִתְעַסֵּק בָּהֶם לְהַעֲלוֹתָם? אֶלָּא לְפִי שֶׁלֹּא הִסְפִּיק לְגָמְרָהּ וּגְמָרוּהָ יִשְׂרָאֵל נִקְרֵאת עַל שְׁמָם (תנחומא): כל המצוה — Explain this in its plain sense: EVERY COMMANDMENT. — And a Midrashic explanation is (taking it to mean, “the whole of the commandment … shall ye be heedful to do”): If thou hast once made a beginning with a meritorious deed, carry it out to the end, because it bears the name only of him (it is attributed only to him) who does the last part of it, as it is said, (Joshua 24:32) "And the bones of Joseph which the children of Israel brought up from Egypt they buried in Shechem”. But did not Moses alone busy himself with them to bring them up (cf. Exodus 13:19)? But because he had no opportunity to complete this (to inter them), the children of Israel completed it, it was called by their name (Midrash Tanchuma, Eikev 6).
