Deuteronomy 32:4-6

International Standard Version

⁴ Flawless is the work of the Rock,
    because all his ways are just.
A faithful God—never unjust—
    righteous and upright is he.
⁵ But those who are not his children
    acted corruptly against him;
        they are a defective and perverted generation.
⁶ This is not the way to repay the Lord, is it,
    you foolish and witless people?
Is he not your father,
    who bought you, formed you, and established you?
