Deuteronomy 33:20-22

New Revised Standard Version, Anglicised Catholic Edition

Blessed be the enlargement of Gad!
    Gad lives like a lion;
    he tears at arm and scalp.
²¹ He chose the best for himself,
    for there a commander’s allotment was reserved;
he came at the head of the people,
    he executed the justice of the Lord,
    and his ordinances for Israel.

Dan is a lion’s whelp
    that leaps forth from Bashan.
