Yehudim in Moshiach 5:4-6

Orthodox Jewish Bible

⁴ And one does not presume to take the kavod of the office of Kohen Gadol upon oneself, but one must have the bechirah (choice, election) of Hashem, just as Aharon did.

⁵ So also Rebbe, Melech HaMoshiach did not seize kavod for himself to become a Kohen Gadol, but the One having said to him, "BENI ATAH, ANI HAYOM YELIDTICHA," ("My Son you are; Today I have become your Father." TEHILLIM 2:7)

⁶ Says also in another passage, "ATAH KOHEN L’OLAM AL DIVRATI MALKITZEDEK ("You are a kohen forever according to the order of Malki Tzedek"‖Ps 110:4).
