Deuteronomy 32:5-7

New Catholic Bible

⁵ They have corrupted themselves,
    on account of their defect they are no longer his children,
    they are a perverse and crooked generation.
⁶ Is this the way to repay the Lord,
    O foolish and stupid people?
Is he not your father, who created you?
    Has he not made you and established you?
⁷ Remember the days of old,
    consider the years of past generations,
Ask your fathers, they will tell you,
    your elders, they will inform you.
