Psalm 78:7-11

so that they should set their hope in God and not forget the works of God, but keep his commandments; and that they should not be like their fathers, a stubborn and rebellious generation, a generation whose heart was not steadfast, whose spirit was not faithful to God. The Ephraimites, armed with the bow, turned back on the day of battle. They did not keep God’s covenant, but refused to walk according to his law. They forgot his works and the wonders that he had shown them.
