Yehudim in Moshiach 7:5-7

Orthodox Jewish Bible

⁵ And the ones of the Bnei Levi have received the Kehunah (Priesthood) and they have a mitzvah to collect the ma’aser (tithe) from the Am Brit, and they have this mitzvah according to the Torah, that is, to collect from their achim, though these also are descended from the loins of Avraham Avinu.

⁶ But, this man, though not tracing his descent from them, has received ma’aser (tithe) from Avraham Avinu and has given a bracha to the one having the havtachot (promises).

⁷ Now it is beyond all argument that the greater gives a bracha to the lesser.
