Numbers 11:26

וישארו שני אנשים BUT THERE REMAINED TWO MEN [IN THE CAMP] — i. e. two of them that had been selected. They remained, in the camp because they said, “We are not worthy of this distinction” (Sifrei Bamidbar 95:2). והמה בכתובים [BUT THERE REMAINED TWO MEN IN THE CAMP] … AND THEY WERE AMONGST THEM THAT WERE WRITTEN — i.e. they were amongst those of them (of the people) who had been selected to constitute the Sanhedrion. For all these were written down, mentioned expressly by their names, but the requisite number was chosen by lot, because the calculation gives for twelve tribes, six elders for each tribe, with the exception of two tribes to each of which there would belong only five elders. Moses said, “No tribe will listen to me to have one elder less for his tribe!” What did he do? He took seventy-two tablets and wrote on seventy of them the word “Elder” and on two he left the surface blank. He then selected six men of each tribe so that there were altogether 72. He said to them, “Draw your tablets from the urn”. He in whose hand there came up a tablet bearing the inscription “Elder” was set apart as a member of the Sanhedrion, whilst to him in whose hand there came up a blank tablet, he said, “The Omnipresent does not require you” (Sifrei Bamidbar 95:2; Sanhedrin 17a).

וַיִּשָּׁאֲר֣וּ שְׁנֵֽי־אֲנָשִׁ֣ים ׀ בַּֽמַּחֲנֶ֡ה שֵׁ֣ם הָאֶחָ֣ד ׀ אֶלְדָּ֡ד וְשֵׁם֩ הַשֵּׁנִ֨י מֵידָ֜ד וַתָּ֧נַח עֲלֵהֶ֣ם הָר֗וּחַ וְהֵ֙מָּה֙ בַּכְּתֻבִ֔ים וְלֹ֥א יָצְא֖וּ הָאֹ֑הֱלָה וַיִּֽתְנַבְּא֖וּ בַּֽמַּחֲנֶֽה׃

And there remained two of the men in the camp, the name of the one was Eldad, and the name of the other Medad: and the spirit rested upon them; and they were of them that were written, but went not out to the tent: and they prophesied in the camp.
