Yehudim in Moshiach 7:21-23

Orthodox Jewish Bible

²¹ But the Rebbe, Melech HaMoshiach became a kohen with a shevu’ah (oath) through the One saying to Him, "Hashem has made an oath and will not change his mind, You are a kohen forever" [TEHILLIM 110:4].

²² According to such a shevu’ah of Hashem, Rebbe, Melech HaMoshiach Yehoshua has become the arev (surety, guarantee) of a tovah yoter HaBrit.

²³ Not only this, but it was the fact that the former kohanim were many in number, because mavet prevented them from continuing in the office of kehunah.
