Deuteronomy 32:3-5

Authorized (King James) Version

³ because I will publish the name of the Lord:
ascribe ye greatness unto our God.
⁴ He is the Rock, his work is perfect:
for all his ways are judgment:
a God of truth and without iniquity, just and right is he.
⁵ They have corrupted themselves,
their spot is not the spot of his children:
they are a perverse and crooked generation.
