מדרש אויף ויקרא 21:10

GEMARA: It is quite right that they should say to him, "Perhaps thou hast forgotten." "But that they should say to him: "Perhaps thou hast not studied," how can an ignorant man be made a High-priest? Have we not learned in a Baraitha: (Lev. 21, 10) And the priest that is highest of his brethren; i.e., he must be highest among his brethren in personal beauty, in physical strength, in wealth and in wisdom. Others say: "Whence do we know that if he is not rich, his brethren, the priests, must make him rich? Read the text, That is highest of his brethren; i.e., his brethren must contribute to make him highest." [Hence he ought to be a great scholar?] "This is not difficult to explain," replied R. Joseph, "for the latter case refers to the time of the first Temple, and the former case refers to the time of the second Temple"; as R. Assis said: "A Tarkabful of dinarim did Martha, the daughter of Baituth, give to king Jannai, until she succeeded in obtaining the appointment of Joshua b. Gamla [her husband] as High-priest."

1) (Vayikra 21:10) ("And the Cohein who is greater than his brothers [i.e., the high-priest], upon whose head the oil of anointment has been poured, and who has been invested to wear the garments — his hair he shall not dishevel and his garments he shall not rend.") "And the Cohein who is greater than his brothers": He must be greater than his brothers in wealth, strength, strength, and wisdom. Whence is it derived that if he is lacking these attributes, his brother Cohanim are to elevate him? From "greater than (lit., "from") his brothers" — his greatness should come from his brothers. They said about Pinchas of Havata upon whom the lot fell to be high-priest, that the (Temple) treasures and trustees went after him and found him quarrying, whereupon they filled the quarry with golden dinars. R. Chananiah b. Gamliel said: Now was he a quarrier? Was he not our son-in-law, and did they not find him plowing? As it was related: Twelve (ox-) pairs went before him, and he came after the twelfth!

(Fol. 9) R. Jeremiah used to say concerning the passage (Lev. 5, 5) And if his means be not sufficient, and again there is a passage (Ib. ib. 7) If he can not afford; all this speaks of persons that might become either poor or rich, which is not the case with either the High-priest or the priest anointed as the chaplain of the army; for concerning the latter, the passage says (Ib. 4, 22) Of all the things which the Lord his God, which signifies him who has for his superior, only his God; and concerning the High-priest, the passage says (Ib. 21, 10) And the priest that is highest among his brethren; i.e., he shall be highest in beauty, in might, in wisdom and in wealth. Acherim says: "Whence is it inferred that if he (the priest) is not rich, his people should make him so? The passage says highest among his brethren, i.e., he should be made great by his own brethren."
