Psalm 78:9

5For he established a covenant in Jacob, and appointed a teaching in Israel, which he commanded our fathers, that they should make them known to their children;

6that the generation to come might know, even the children who should be born; who should arise and tell their children,

7that they might set their hope in God, and not forget God’s deeds, but keep his commandments,

8and 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.

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

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

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

12He did marvelous things in the sight of their fathers, in the land of Egypt, in the field of Zoan.

13He split the sea, and caused them to pass through. He made the waters stand as a heap.
