Psalms 78:9 WEB

⁷  That they might set their hope in God, And not forget the works of God, But keep his commandments,

⁸  And might not be as their fathers, A stubborn and rebellious generation, A generation that didn't make their hearts loyal, Whose spirit was not steadfast with God.

⁹  The children of Ephraim, being armed and carrying bows, Turned back in the day of battle.

¹⁰  They didn't keep God's covenant, And refused to walk in his law.

¹¹  They forgot his doings, His wondrous works that he had shown them.
