Тосефта к Мелахим А 19:19

וַיֵּ֣לֶךְ מִ֠שָּׁם וַיִּמְצָ֞א אֶת־אֱלִישָׁ֤ע בֶּן־שָׁפָט֙ וְה֣וּא חֹרֵ֔שׁ שְׁנֵים־עָשָׂ֤ר צְמָדִים֙ לְפָנָ֔יו וְה֖וּא בִּשְׁנֵ֣ים הֶעָשָׂ֑ר וַיַּעֲבֹ֤ר אֵלִיָּ֙הוּ֙ אֵלָ֔יו וַיַּשְׁלֵ֥ךְ אַדַּרְתּ֖וֹ אֵלָֽיו׃

И пошел он оттуда и нашел Елисея, сына Шафата, который пахал, с двенадцатью ярмами волов перед ним, а он с двенадцатым; И Илия подошел к нему и надел на него свою одежду.

Tosefta Yoma

It is a commandment that the High Priest ("Kohen Gadol") be greater ("gadol") than his brothers, in prophecy, in strength, in wealth, in wisdom, and in appearance. Where is it derived that if he lacks these, that his brothers should [take it upon themselves to] make him great? As it is said (Lev. 21:10): "And the Kohen who is greater ("gadol") than his brothers [etc.]" -- that his brothers make him great. They said of Pinchas the Man of Chavata, upon whom the lot fell to become the High Priest, that the Temple treasurers and officers went looking for him and they found that he was a stone-cutter, and on his account they filled up the quarry [where he was working] with gold dinars. Said Rabbi Chananiah ben Gamaliel, "Was he really a stone-cutter? Rather, he was our son-in-law, and they found him plowing, just as it is said of Elisha (1 Kings 19:19), 'There were twelve yokes of oxen [ahead of him], and he was the twelfth.'" When there became many kings, they decreed that Kohanim would be appointed [as High Priests], and they would set them aside [for appointment] each and every year.
