Sirach 45:23-25

Revised Standard Version

²³ Phin′ehas the son of Elea′zar is the third in glory,
    for he was zealous in the fear of the Lord,
and stood fast, when the people turned away,
    in the ready goodness of his soul,
    and made atonement for Israel.
²⁴ Therefore a covenant of peace was established with him,
    that he should be leader of the sanctuary and of his people,
that he and his descendants should have
    the dignity of the priesthood for ever.
²⁵ A covenant was also established with David,
    the son of Jesse, of the tribe of Judah:
the heritage of the king is from son to son only;
    so the heritage of Aaron is for his descendants.
