Deuteronomy 32:3-5

Lexham English Bible

³ For I will proclaim the name of Yahweh;
    ascribe greatness to our God!
⁴ The Rock, his work is perfect,
    for all his ways are just;
he is a faithful God, and without injustice;^[a]
    righteous and upright is he.
⁵ They have behaved corruptly toward^[b] him;
    they are not his children; this is their flaw,
    a generation crooked and perverse.
