Psalms 78:8
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
And might not be as their fathers, a stubborn and rebellious generation; a generation that set not their heart aright (note: Heb. that prepared not their heart), and whose spirit was not stedfast with God.
Then they will not be like their fathers, a stubborn and rebellious generation, whose heart was not loyal, whose spirit was not faithful to God.
