Wlastow G.K.
The lineage of Levi comprises three distinct tribes; however, Aaron and Moses do not originate from Levi's firstborn son, but rather from the second son.
The sons of Caath: Amram, and Isaar, and Hebron and Oziel. And the years of Caath's life, were a hundred and thirty-three.
וּבְנֵ֣י קְהָ֔ת עַמְרָ֣ם וְיִצְהָ֔ר וְחֶבְר֖וֹן וְעֻזִּיאֵ֑ל וּשְׁנֵי֙ חַיֵּ֣י קְהָ֔ת שָׁלֹ֧שׁ וּשְׁלֹשִׁ֛ים וּמְאַ֖ת שָׁנָֽה׃
