50:16נ׳:ט״ז
1 א

ויצוו אל יוסף. כְּמוֹ וַיְצַוֵּם אֶל בְּנֵי יִשְׂרָאֵל – צִוָּה לְמֹשֶׁה וּלְאַהֲרֹן לִהְיוֹת שְׁלוּחִים אֶל בְּנֵי יִשְׂרָאֵל, אַף זֶה וַיְצַוּוּ אֶל שְׁלוּחָם, לִהְיוֹת שָׁלִיחַ אֶל יוֹסֵף לוֹמַר לוֹ כֵן. וְאֶת מִי צִוּוּ? אֶת בְּנֵי בִלְהָה, שֶׁהָיוּ רְגִילִין אֶצְלוֹ, שֶׁנֶּאֱמַר וְהוּא נַעַר אֶת בְּנֵי בִלְהָה:

ויצוו אל יוסף AND THEY COMMANDED SOME TO GO TO JOSEPH — The words ויצוו אל have the same meaning as in (Exodus 6:13) “and He gave them a charge unto (ויצום אל) the children of Israel”, which signifies, “He commanded Moses and Aaron to act as messengers to the children of Israel”, and this verse, too, means they charged the man whom they sent that he should act as their messenger to Joseph to speak to him as follows (the words לומר לו כן correspond to לאמר in the Bible text here). And who was it that they so charged? The sons of Bilhah who had been accustomed to associate with him, as it is said (Genesis 37:12) “When a lad he used to be with the sons of Bilhah” (Tanchuma Yashan 2:1:2).

אביך צוה. שִׁנּוּ בַדָּבָר מִפְּנֵי הַשָּׁלוֹם, כִּי לֹא צִוָּה יַעֲקֹב כֵּן, שֶׁלֹּא נֶחֱשַׁד יוֹסֵף בְּעֵינָיו (בראשית רבה, יבמות ס"ה):

אביך צוה THY FATHER DID COMMAND — They altered the facts (they stated something that was false) for the sake of peace, for Jacob had given them no such command because Joseph was not suspect in his sight (Yevamot 65b)).
